I'd like to fix this bug.

So, we should cache calculated collapsed borders.
However they depend on many styles - cells, rows, row groups, etc.
How can we track all these dependencies to clear cache?

One possible approach is listening styleDidChange() in every cell, row,  etc and notify parent table that cache become invalid. Plus do same for addChild() and removeChild(). 

What do you think?

Any alternative ideas how to solve this?
