Turns the issue color of closed issues from purple back to red - back reddish color icon for closed github issues.
Reverts* closed issues from purple to red on:
* — In some/rare instances the icon may be purple due to static assets being used or not convertible from extension JS to CSS4.
Errors specific to *.user.CSS and *.user.JS are best reported here, so as not to burden the add-on creator with unnecessary messages.
That userCSS now requires layout.css.has-selector.enabled flag to be enabled in about:config. In older versions, native has may have execution errors (therefore, it is worth considering upgrading to a newer version of Firefox instead of using the outdated or conservative ESR 115 experimental preference).
With the implementation of using :has() from CSS4, Stylus style stops working well for Chromium older than 103-105 and Safari 15.4.
If the automatically generated userScript after release 7.0.0+ does not work well, then I recommend switching to the CSS version for Stylus.
