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.
