We should never set the clip rectangle to something larger than the
initial graphics context bounds, since we won't render to an area
larger than that and the contents will be left stale.

Correct this by clipping to the initial clip rectangle whenever the clip
rectangle is reset.

* Source/WebCore/platform/graphics/displaylists/DisplayListRecorder.cpp:
(WebCore::DisplayList::Recorder::resetClip):
We were already setting the clip bounds to this value a few lines above.

* Tools/TestWebKitAPI/Tests/WebCore/DisplayListRecorderTests.cpp:
Update test expectation.
