When we check in the fix + tests, we should check "auto" in addition to "hidden" for the overflow value.

I think this has been mostly fixed.  However, this particular testcase still shows the problem, because for some reason the fix isn't working when the replaced element or element with overflow:hidden is at the very top of the block.
