A specific cosmetic filter of the following form...
*##.selector
... will be unconditionally injected into all web pages,
whereas a cosmetic filter of the form...
##.selector
... would be injected only when uBO's DOM surveyor finds
at least one matching element in a web page.
The new specific-generic form will also be disabled when a
web page is subject to a `generichide` exception filter,
since the filter is essentially a generic one -- the only
difference from the usual generic form is that the filter
is injected unconditionally instead of through the DOM
surveyor.
Specific-generic cosmetic filters will NOT be discarded
when checking the "Ignore generic cosmetic filters"
option in the "Filter lists" pane -- since the purpose
of this option is primarily to disable the DOM surveyor.
Specific-generic cosmetic filters should be used
parcimoniously and only when using a normal specific
filter is really impractical.

Hostnames which have unpunycoded IDN or canonical
name information will have this information reported
as an extra line under the hostname name in the popup
panel, rather than as a tooltip.
For the fenix UI flavor, the save/revert tools are
now shown regardless of whether the overview area is
visible or not.
More specifically, this commit makes it so that
the new default UI for Firefox Preview will be
automatically selected.
A default platform-specific UI can be cancelled
by setting the advanced setting `uiFlavor` to `-`.
The toolip of a canonical name entry (blue)
in the popup panel will provide the alias
hostname related to the canonical hostname
in order to help with rule-making decisions.

Leading wildcards before valid token characters need to
be kept in order to respect the semantic of the filter.
A leading wildcard in such case changes the semantic of
a filter, i.e. two following filters are semantically
different:
example/abc
*example/abc
As a result, µBlock.BidiTrieContainer.indexOf() is now
able to deal with a needle of length zero -- which is
what happens in FilterPatternLeft(Ex) with filter
patterns starting with `*` (or `^*`) and followed by
valid token characters (0-9, a-z and %).
