3 <td rowspan=
48651511>This test succeeds if it does not crash. We implemented a heuristic a while back to prevent giant rowspans.
4 The heuristic did not, however, fix this case. This rowpsan was small enough so that we thought it was okay to allocate, but
5 large enough so that it actually wasn't okay, and we crashed. Firefox seems to hold
8k as the maximum size for rowspans.
6 So this change matches Firefox and clamps all rowspans to
8k right in the DOM.
