Patch for EditPage.php
The textarea on an edit page normally has a class assigned to it when the title is (semi)protected (mw-textarea-sprotected or mw-textarea-protected), but not when the title is cascade-protected. This makes styling of cascade-protected edit pages impossible.
Attached patch will add the mw-textarea-cprotected class in case the title is cascade-protected.
