Table test is invalidating the wrong rect

Not quite sure how this is occurring, but I believe this to be related to larger repaint issues seen with:

In this reduction, note that every time we add a new table, the first table in the parent div redraws.  This is an unnecessary invalidation causing overdrawing.
