Fixed rendering issue by delaying setting WebPage::m_mainFrame to exactly what was done before. The issue was that we were unfreezing too quickly in case of ProcessSwapping.
This does not fix the potential raciness in the two DrawingArea messages of the being-swapped WebPageProxy, but this patch does not make it worse.

Can you file a follow up bug about the DrawingAreaProxy race — probably for Chris or Tim? Sounds like something worth fixing.

Sure.
To be clear, the race is hopefully probably theoretical only.
My main issue is that the design seems a bit weak since we keep two IPC listeners from two different processes but for the same page.

I'll do some follow-up clean-up related to WebPage.
