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.
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have execution errors (therefore, it is worth considering upgrading to a newer version of Firefox instead of using the outdated or conservative ESR 115 experimental preference).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.
Due to a user script failure in Tampermonkey and Violentmonkey, I am deactivating this form of subscription for the time being (perhaps there are errors in my regex). I'm not planning on debugging, just checking if removing regex support is enough to restore functionality in Tampermonkey and Violentmonkey.
