* Source/WebCore/page/InteractionRegion.cpp:
(WebCore::interactionRegionForRenderedRegion):
The code to avoid interaction regions that take more than half the viewport
had a minor flaw that only comes up for clients who use the autosizing API:
in fixed-width flexible-height mode, the main frame's fixed layout size
always has a height of 1px, causing the area check to fail on all but the
smallest of interactible elements.

Instead of looking at the layout size, use the actual size of the FrameView.
