Reviewed by Tim Horton.

Tweak the maximum size threshold (relative to the frame area) before we
skip Interaction Regions.

* Source/WebCore/page/InteractionRegion.cpp:
(WebCore::interactionRegionForRenderedRegion):
Make the maximum 1/3rd instead of half of the frame area.

* LayoutTests/interaction-region/interaction-region-size-limit-expected.txt: Added.
* LayoutTests/interaction-region/interaction-region-size-limit.html: Added.
Add a test with some mockup UI.
