In the reduced testcase, the left cell doesn't get invalidated before layout,
since it is not marked as needing layout at that point (only the right cell
is). If you initiate the change on the left cell (e.g. by doing
document.getElementById('col1').style.width='500px'), then the left cell is
marked as needing layout early on and therefore gets repainted before layout,
and you don't get the buggy behavior.

I have an ugly fix for this specific case but I think the problem may be more
general (whenever an object gets marked as needing layout during relayout and
its parent wasn't marked as needing layout for itself before), so I'm still
trying to figure out a general solution.
