Tab switch can be expensive if a page has a beforeunload handler. We should start warming up the next tab to be shown early in the process of tab removal to compensate for this.

Tab switch can be expensive if a page has a beforeunload handler. We should
start warming up the next tab to be shown early in the process of tab removal
to compensate for this. We could only do this if we know we have a
beforeUnload handler, but there shouldn't be any negative side effects of
getting started on the tab switch early regardless.
