Revert 106232 - .: Manual test of number of resize events emitted during page generation.

not currently support testing fixed layout.

Source/WebCore: Only send resize events when layout size changes.

When using fixed layout the widget size is the size of content, therefore
resize checks must check against layoutsize and not widget size.
