Reviewed by Tim Horton.

Tweak the interaction regions generation heuristics to avoid extra
regions for:
- pseudo-elements
- children of block elements getting their own InteractionRegion

* Source/WebCore/page/InteractionRegion.cpp:
(WebCore::interactionRegionForRenderedRegion):
Keep track of the original RegionRenderer node separately of the one we
end up matching in order to tweak the heuristics.

* LayoutTests/interaction-region/nested-composited-text-painter-expected.txt: Added.
* LayoutTests/interaction-region/nested-composited-text-painter.html: Added.
* LayoutTests/interaction-region/pseudo-element-expected.txt: Added.
* LayoutTests/interaction-region/pseudo-element.html: Added.
Add tests for these cases.
