Bug 36479 – Plug-in clip rect does not update when overflow clip changes

• Component: Plug-ins
• Status: RESOLVED FIXED

<rdar://problem/7197736>

When changes to overflow clip affect a plug-in’s visible rect, but its frame rect doesn’t change, if the plug-in is not in a compositing layer, then it does not get updated to reflect the change to clipping. This is demonstrated by a manual test which is part of a forthcoming patch.

Typo: "dsiabled". I'll review more later.

Oops, I r+'ed the obsolete version.

r+ if you fix "dsiabled" and "ba any red".

Fixed in <http://trac.webkit.org/projects/webkit/changeset/56429> except I forgot to fix the typos in the test :-(
