https://bugs.webkit.org/show_bug.cgi?id=96698 Reviewed by Anders Carlsson. When given a rect outside of the current tile coverage rect, TileCache::setNeedsDisplayInRect() would try to invalidate the top left tile. This would normally be a no-op, except when repaint counters are visible, in which case it would invalidate the counter area. Fix by doing an early return if the intersection between the repaint rect and the tile coverage rect is empty. * platform/graphics/ca/mac/TileCache.mm: (WebCore::TileCache::setNeedsDisplayInRect): git-svn-id: http://svn.webkit.org/repository/webkit/trunk@128529 268f45cc-cd09-0410-ab3c-d52691b4dbfc
