Noticed while debugging stuff on android. On platforms with overlay scrollbars, the scrollbars don't take up any layout space. Yet we still run through the four-step TryLayout code which tries to figure out which combination of scrollbars we want by reflowing at different sizes (which with overlay scrollbars are all the same size).

It should be possible to optimize this so that we don't do all this unnecessary work.
