           Summary: FrameView::layout() not always resuming scheduled events
           Product: WebKit
           Version: 522+ (nightly)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kevino at theolliviers.com


Recently, the wx port started triggering an assert in FrameView::~FrameView,
caused by the fact that d->m_enqueueEvents > 0. Tracking this down, I've found
the reason for this appears to be that in FrameView::layout(), while
pauseSelectedEvents() is always called, resumeSelectedEvents() is only
triggered if root->needsLayout() (the if statement in line #453) is false. If
root->needsLayout() is true, a layout is scheduled and the function exits
without resuming scheduled events.

Since I'm not too familiar with the bugs fixed by pause/resumeSelectedEvents(),
I'm not sure how best to fix this problem (though Mitz said on IRC that he
might :-), so I thought I'd just file a bug for this so that those familiar
with the code can take a look.
