The following case of invalid syntax was not reported as
invalid by the syntax highlighter:
... example.com image ...
With dynamic filtering, there can't be a specific
hostname when a specific type is used, or a
specific type when a specific hostname is used, one
or the other must be `*`.
uBO support's `#?#`, which in AdGuard and ABP means that a
cosmetic filter is procedural.
However, uBO interprets this syntax as "probably procedural"
and will use the filter in a declarative way if the filter
is found to be stylesheet-compatible.
In reality though, the likelihood that a "probably procedural"
filter is sheet-selectable is very low, so treating the filter
as procedural a priori help saves pointless tests against
sheet-selectability when using lists primarily designed for
AdGuard or ABP.

For instance, with "Experimental Web Platform features" enabled, the
following filter becomes natively query-selectable:
.fail:has(+ a > b)
Meaning uBO won't need to emulate the `:has()` operator, it will
be executed natively using `querySelectorAll()`.
This commit fixes the erroneous assumption that a query-selectable
is also sheet-selectable.

It turns out Chromium has started to implement the `:has()`
operator, which becomes recognized when the browser flag
"Experimental Web Platform features" is enabled. However the
hic is that `:has()` is not supported as a declarative CSS
style rule and is only supported through `querySelector()`
et al.
The fix is to no longer detect plain CSS selectors through
`querySelector` et al. but rather use an actual stylesheet
to validate that a cosmetic filter can be injected into a
stylesheet in a declarative way.
Additionally, I added support to enforce ABP's semantic
regarding cosmetic filter with the `#?#` anchor: when using
such anchor, uBO will _first_ try to compile the filter as
a procedural one rather than a declarative one.

Sometimes a tab event may fire for a tab which is not
yet known to uBO. In such case, bind the tab internally
so that it can be processed properly in the future.

Specifically:
- Support i18n
- Autofill issues opened through Support pane with configuration
information
- Remove from About pane items found in Support pane
For now the language locales are not available as the text on
the page needs to stabilize before asking translation
volunteers to contribute their time working on the new text.
By default uBO assumed the Shortcut pane was needed,
unless it found the current version of FF was higher
than 73. This commit reverses the test, it assumes
the Shortcut pane is not needed, unless the current
version is lower than 74.
isBlockImportant() was relying strictly on the hash bits
to detect whether a matching filter was `important`, but
this approach regressed with changes with how `important`
filters are compiled. This commit fixed this by no longer
relying on the hash bits but rather on an internal
register variable being set by `important` filters when
they match.
I couldn't find any actual cases in default filter lists
(including a couple of default regional lists) that the
regression is having any effect, due to the limited cases
for which isBlockImportant() is called.
A test was added in a previous commit to detect such
regression in the future:
- a76935b232

The regression affect filter with the `important` option when
the following conditions were fulfilled:
- The filter pattern is pure hostname
- The filter has not one of the following options:
- domain
- denyallow
- header
- strict1p, strict3p
- csp
- removeparam
- There is a matching exception filter

A related mocha test has been added in order to detect this
specific regression in the future through `make test`.

A new filter unit, FilterNotType, is introduced to enforce
negated filter type options.
Before this commit, there was no actual negated types in the
static network filtering engine, as a negated type was internally
converted to non-negated types at compile time. As a result,
the logger would never output a matching filter with its original
negated type options.
This commit no longer causes an internal conversion to take place
at compile time, but explicitly enforce negated types at match time,
and as a result the logger will from now on output matching filter
with their original negated type options.
Name: modifyWebextFlavor
Value: A list of space-separated tokens to be added/removed from the
computed default webext flavor.
The primary purpose is to give filter list authors the ability to
test mobile flavor on desktop computers. Though mobile versions of
web pages can be emulated using browser dev tools, it's not
possible to do so for uBO itself.
By using `+mobile` as a value for this setting will force uBO
to act as if it's being executed on a mobile device.
Important: this setting is best used in a dedicated browser
profile, as this affects how filter lists are compiled. So best
to set it in a new browser profile, then force all filter lists
to be recompiled, and use the profile in the future when there
is a need to test the specific webext flavor.

The ids/classes from html/body elements will leave out
looking up lowly generic cosmetic filters made of a single
identifier.
This does not absolutely guarantee that html/body elements
will never be targeted, but it should greatly mitigate the
probability that this erroneously happens.
