Bug 14954 – NSView redisplay doesn't update display when selection changes

I'm trying to flash the selected text synchronously, but asking the NSView to redisplay doesn't draw anything after I change the selection.  This code works fine in released versions of Safari 2 (419.3).

WebHTMLView *view;
[...]
NSRect selectionRect = [view selectionRect];
for (i = 0 ; i < textBlinkCount ; i++) {
    [view deselectAll];
    [view setNeedsDisplayInRect: selectionRect];
    [view display];
    usleep(60000);
    [[view _bridge] selectNSRange: selectedRange];
    [view setNeedsDisplayInRect: selectionRect];
    [view display];
    usleep(60000);
}

I asked about this on #webkit and Darin suggested using [[view window] displayIfNeeded], which behaved identically to the above code (works in 419.3, not in nightly).

I think this may have been a coding error on my part; whatever the issue was, it now works fine with Safari 3.0.4/3.1.
