Override the Backspace key, not just the Delete key, as Mac keyboards have Backspace as the only delete key and label it Delete.
Source of key value: https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key/Key_Values#Editing_keys
More background on Mac keyboard shortcuts: Mac keyboards can emulate Delete using fn+Delete, meaning Forward Delete, but Mac software does not use it except in text editing. When deletion is dangerous, Mac software requires holding a modifier key in conjuction with Delete, but I think it’s better to make deletion easy in this case.
This new binding has a potential downside: if the user Backspace key normally goes Back in history (which can differ across OSs and browsers), this will change the behavior to delete the selected element instead. If the user really wants to go back in history, they will have to press Escape to leave the mode and then press Backspace, or they will have to press an alternative keyboard shortcuts such as Alt+Left. I think the user will rarely want to go back in history in the middle of picking an element, though.
That downside could be mitigated by conditioning the key check on `runtime.PlatformOs` (https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/runtime/PlatformOs). But that would complicate the code a lot compared to the importance of this feature, and such detection would still fail to capture the user’s intent accurately in all cases. I think it’s better to unconditionally accept both Backspace (Delete) and Delete (Forward Delete).

As per various feedbacks:
Added an advanced setting to keep the original behavior,
which can be potentially costly CPU-wise on some sites:
popupCosmeticFilterBadgeSlow
Default to `false`. Set to `true` to restore original
method of surveying the number of elements hidden as
a result of applying cosmetic filtering.
As suggested by <https://github.com/gwarser>, skip
descendant of nodes which have been found to be a
match in order to potentially increase the number
of nodes which can be surveyed in the alloted time.

When trying the number of hidden elements as a result of
cosmetic filtering for popup panel badge purpose, the
code will bail out if this takes too long, and in such
case the badge will be set to `?`, meaning the number
of hidden elements is undetermined.

The code used to count expensive-to-survey particular
inline javascript occurrences will be executed if and
only if no other script tags have been found in the
DOM. This is acceptable since the badge count is to be
deemed approximate (as per documentation).

Mind that there might not be selectors to match as a
result of `generichide` or `no-cosmetic-filtering`.

The badge value for the no-cosmetic-filtering
switch will be evaluated on-demand only, when
the user hover over the switch with the mouse
cursor.
For touch screen displays, a tap on the switch
will cause the badge to be rendered if not
already done, otherwise this will toggle the
switch as usual.

This is the code used to find out the count values
displayed as badge on the cosmetic filtering and
scripting per-site switches in the popup panel.
The issue is that document.querySelector*() -- used to
find out the number of hidden elements -- is unduly
expensive on large DOM.
The changes in this commit have focused on avoiding the
use of document.querySelector*() as much as possible.
Also, the results are cached for reuse unless DOM
mutations are detected.

Procedural cosmetic exception filters were the
last class of cosmetic exception filters not
being reported in the logger; this commit fixes
this.
Additionally, ensure that a single DOM listener
can't prevent other listeners from being
processed by throwing an exception. Such approach
would have prevented regression leading to
emergency release 1.22.4:

Ensure that the code which depends on extending
`vapi-client.js` is ready to deal with
`vapi-client-extra.js` failing to load.
As reported by https://github.com/uBlock-user,
adding the two following filters:
example.com##div:style(width: 1016px !important)
example.com##div:style(display: block !important)
The logger would report only one of the filter when
navigating to https://example.com/
Little-used code from vapi-client.js has been moved
to vapi-client-extra.js. Given that vapi-client.js
is injected in all web pages, this means less dead
code being injected in all pages.
Swathes of code in vapi-client.js was used only in
a few very specific cases, such as when the logger's
DOM inspector is opened or when the "Filter lists"
pane in the dashboard is opened -- and thus to avoid
that little used code to be loaded in every web page
unconditionally, it has been moved to its own
separate file, vapi-client.extra.js.
vapi-client-extra.js is loaded declaratively or
programmatically only where needed.
No need to store mouse coordinates in background
page, thus no need to post mouse coordinates
information for every click.
Rename/group element picker arguments and popup
arguments separately.
Issue reported by @uBlock-user in team channel.
Creating cosmetic procedural exception filters was
causing `cosmetic-logger.js` scriptlet to throw at
and thus further breaking the logging of cosmetic
filters overall.

Messages from unprivileged ports (i.e. from content scripts)
are no longer relayed to message handlers which are to be
strictly used to execute privileged code.
The last remaining case of unprivileged messages which
should be converted into a privileged ones will be taken
care of when the following issue is fixed:

Make the element picker better reflect network filters as
parsed by the static network filtering engine. Additionally,
discard single alphanumeric character-based filters.

Inject newly created cosmetic filters into the DOM
filterer, in order for these filters to be enforced by
the DOM filterer in subsequent dynamic DOM changes.

Fixed:
- Expect the differ can return the first input as is when
there is no difference between the two items.
- Better deal with extraneous whitespaces in `srcset`

The issue fixes previewing the hiding/unhiding of targeted
elements in the element picker.
However it does not address the case of previewing
`:style(...)` operators -- this would require a much
more complex fix, which I am not sure is worth the
amount of work and increased code complexity.

Additionally, the extended exception filters in the
logger will be rendered with a line-through to more
easily distinguish them from non-exception ones.
Also, opportunistically converted revisited code to
ES6 syntax.
Those spurious disconnections have been observed to occur at
uBO's launch time.

I have observed that this fixes an issue observed on Firefox 64
(current stable).
The reported Waterfox issue *may* be fixed as a result. If not,
the issue he still considered fixed as Waterfox is not
officially supported.

A new advanced settings has been added: `autoCommentFilterTemplate`.
Default value is `{{date}} {{origin}}`.
Placeholders are identified by `{{...}}`. There are currently
only three placeholders supported:
- `{{date}}`: will be replaced with current date
- `{{time}}`: will be replaced with current time
- `{{origin}}`: will be replaced with site information on which
the filter(s) was created
If no placeholder is found in `autoCommentFilterTemplate`, this
will disable auto-commenting. So one can use `-` to disable
auto-commenting.
Additionally, if auto-commenting is enabled, uBO will not emit a
comment if an emitted comment would be a duplicate of the last
one found in the user filter list.
