Fails on Chromium too, marking as WebCore CSS.

Can you retitle the bug to describe the actual problem here?

Does this fix any of the bugs listed as dependent on bug 47141?

The margin-applies-to* tests aren't listed there, so maybe this was a regression. Is there a reason all the tests in the suite haven't been landed? Is it wrong to add them to LayoutTests/CSS2.1/20110327 as I'm doing with this patch?

Unlikely. I didn't finish filing all the bugs for CSS 2.1 failures.

We just haven't merged the full 2.1 suite, because it's huge. I think it's OK to add them in there, since they'd be replaced with the actual tests if we land the new suite.

Please update your patch with the more appropriate bug title.
