Summary [CSS Regions] ASSERT when hovering over region

Created attachment 224202 [details] Hover over the second region to trigger a crash There are cases when the hit-testing code asserts when hovering a region. This happens because we call borderBoxRectInRegion for a box with a region range that doesn't contain the target region. A good fix would be to make hit-testing rejection first based on the range of the box. It doesn't make sense to have a hit on a box in a region where that box doesn't actually appear.
