Thread:Talk:ResourceLoader/Features/Removed fixme/reply (3)

The distinction is that styles loaded by file modules from  trigger separate load.php requests that load each stylesheet from the direct file reference (not through load.php) which means that (as documented) no minification, embedding or flipping applies.

However there is one exception, and that is the Skin stylesheet. That stylesheet isn't loaded from  but from a hardcoded  -tag, which (obviously) has no javascript execution and as such goes through load.php and gets all the flipping applied.
