Test case

See HTMLTableCellElement.cpp:

// Clamp rowspan at 8k to match Firefox.
static const int maxRowspan = 8190;

The limit was bumped up on other browsers including FF and we now have the lowest limit. Not sure why the limit is kept this low  the rendering code should be able to handle higher values for rowspans.

I haven't tried to determine what would be a better limit and that would need to be investigated.
