[LayoutNG] Ensure self-collapsing block relayout when ancestor resolves.

This bug was a combination of older code before we had "forced" BFC
block-offsets.

We didn't correctly detect when we had a self-collapsing block (which
had floats within it) that needed relayout if the initial estimate
was wrong.

This makes sure we give ourselves enough information to detect these
cases.
