Many wikis use pages like MediaWiki:Common.css to create a custom 'theme' for their wiki. However, due to security concerns discussed in task T72672, site-wide CSS on restricted special pages was disabled. By default such style sheets no longer load on login or preference pages creating an inconsistent user interface. This configuration parameter allows to re-enable site-wide CSS on restricted special pages.

If using MobileFrontend extension note that $wgMFSiteStylesRenderBlocking also needs to be enabled for this to work.
