Andreas Kling 16662ab230 LibWeb: Account for collapsed top margins in BFC root height calculation
By the time we're measuring the height of a BFC root, we've already
collapsed all relevant margins for the root and its descendants.
Given this, we should simply use 0 (relative to the BFC root) as the
lowest block axis coordinate (i.e Y value) for the margin edges.

This fixes a long-standing issue where BFC roots were sometimes not tall
enough to contain their children due to margins.
