Mark OOFs for paint invalidation on layout cache hit.
This is a work-around for cases where an OOF is missed during
LayoutObject subtree tree walk in pre-paint (with block fragmentation),
so that we end up in PrePaintTreeWalk::WalkMissedChildren(). If any of
the ancestors of the OOF actually moved, pre-paint will force a deep
subtree walk, but that's not going to help the OOF if it's missed.
