Auto merge of #13302 - pcwalton:negative-margin-speculation, r=notriddle

Browse source 
layout: Disable the speculation of block formatting contexts' inline sizes if the block formatting contexts have negative margins.

The heuristics that determine how and whether floats flow into the
margins are not valid in that case.

Closes #13299.
