Bug 156568

Summary: Color changes should not invalidate collapsed border cache
Product: WebKit Reporter: Antti Koivisto <koivisto>
Component: TablesAssignee: Nobody <webkit-unassigned>
Status: RESOLVED INVALID

RenderTable::invalidateCollapsedBorders() traverses all cells. This can lead to O(n^2) during style recalc. Mitigate by avoiding unnecessary traversal when nothing that matters changes.
