<h3>Log Message</h3>
<pre>Merge <a href="http://trac.webkit.org/projects/webkit/changeset/201346">r201346</a> - fast/table/neighboring-cells-when-collapsed-border-changes.html is flaky.
https://bugs.webkit.org/show_bug.cgi?id=158009
Reviewed by David Hyatt.
RenderTable::invalidateCollapsedBorders() early returns on m_collapsedEmptyBorderIsPresent
which prevents us from marking neighboring cells dirty when style changes.
Decouple the "invalidate the collapsed borders" and the "mark the neighboring cells dirty" logic.
Source/WebCore:
Covered by existing tests. (and now we agree with FF on cached-change-cell-border-width.html)
