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. <rdar://problem/7664353>
Created attachment 49085 [details] proposed fix Did some brief testing on Windows, and this doesn't seem to break things.
