           Summary: PlatformMouseEvent "current event" handling is bogus
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: marv.decker at gmail.com


The constructor PlatformMouseEvent::PlatformMouseEvent(const CurrentEventTag&)
gets the current event from nsApp and creates a mouse event from it. However,
this is only valid when the currently handled event is a mouse event. When it
is not a mouse event, the mouse position will be undefined in the nsEvent.

Usually, this code is called from mouse event handlers so that's fine.
Currently, it is also called from the hoverTimer callback in the EventHandler.
The current event is likely to not be a mouse event, yet a PlatformMouseEvent
is still created from the current event.
