Description Alexey Proskuryakov 2010-02-18 14:37:06 PST
WebKit sometimes changes mouse cursor over Netscape plug-ins, even though those are supposed to be in control of cursor.

1. EventHandler sets cursor before dispatching events to plug-in.
2. SetCursor overrides in WEbHTML view are currently ineffective, to AppKit resets the mouse pointer to default once it cannot find an appropriate cursor rect.

This causes flickering - and I actually saw the cursor disappear on google.com/finance.

The problems are most visible with Flash 10.1 beta.

Did some brief testing on Windows, and this doesn't seem to break things.
