This seems like it would work, but it actually didn't. One issue was that WPF uses rows with dynamic row heights instead of fixed row heights like GDI or WinForms. This forced it calculate everything it needed for the layout of each row to compute the total height, scroll position, etc...

Like I said, this got changed when Visual Studio was rewritten to use WPF, and it "works now", but the default behaviour is still the slow path, not the fast path.
