<pre>The problem is that WebPage has its own m_useFixedLayout that is only updated when changed from the UI process. However, layout tests doing internals.setUseFixedLayout() change the frame view directly, and the WebPage doesn't notice it. The WebPage should use the frame view directly to ensure it's always in sync, instead of having its own m_useFixedLayout.
