The patch applies to RenderObject::containingBlockWidth() and
RenderObject::containingBlockHeight() which logic was changed and moved to
RenderBox in 4.6 and trunk since then.

I'm marking this bug as fixed since 4.5, but if you can get a test case that
would allow us to try reproducing it in 4.6 and trunk that would be awesome and
we'll re-open this bug.
