Automatic update from web-platform-tests [layout] Fix self-collapsing end-margins contributing to overflow. Previously we just took the end margin-strut, and used this for the scrollable-overflow. This was incorrect. As the end margin-strut is used for positioning self-collapsing blocks we ended up "double counting" these margins. This patch uses the "final" margin-strut, and subtracts the self-collapsing end margin-strut to correctly determine the block-end margin which contributes to scrollable-overflow.
