Possibly because the Opera sidebar window is a special
case, it appears the scriptlets must be injected at a
later time.
Use a global isolated window variable to detect whether
the scriptlets have really be injected, and ultimately
inject them at main content script time when it is found
they haven't been injected at that point.
This commit make it so scriptlet injections will occur
at the earliest possible time on all platform.
This should also fix the case reported at:
- https://www.reddit.com/r/uBlockOrigin/comments/ye6abt/
Which is caused by the fact that there is no webNavigation
events being fired by the browser. In such case, the changes
here will make it so that uBO will detect that the scriptlet
were not injected and will inject them at main content script
injection time.
This commit adds the ability to inject entity-based plain CSS
filters and also a set of the most commonly used entity-based
scriptlet injection filters.
Since the scripting API is not compatible with entity patterns,
the entity-related content scripts are injected in all documents
and the entity-matching is done by the content script themselves.
Given this, entity-based content scripts are enabled only when
working in the Complete filtering mode, there won't be any
entity-based filters injected in lower modes.
Also, since there is no way to reasonably have access to the
Public Suffix List in the content scripts, the entity-matching
algorithm is an approximation, though I expect false positives
to be rare (time will tell). In the event of such false
positive, simply falling back to Optimal mode will fix the
issue.
The following issues have been fixed at the same time:
Fixed the no-filtering mode related rules having lower priority
then redirect rules, i.e. redirect rules would still be applied
despite disabling all filtering on a site.
Fixed improper detection of changes to the generic-related CSS
content script, potentially causing undue delays when for example
trying to access the popup panel while working in Complete mode.
The scripting MV3 can be quite slow when registering/updating
large content scripts, so uBOL does its best to call the API only
if really needed, but there had been a regression in the recent
builds preventing uBO from properly detecting unchanged content
script parameters.
It's possible to salvage network rule with entity syntax-based
entries in their `domain=` option if there exists at least one
entry which is not entity syntax-based.
For negated entries, these can be unconditionally removed
safely.
