We only use the MainThreadScrollingReason "ForcedOnMainThread" if we install a page overlay (didInstallPageOverlay), which clients can do arbitrarily.

We probably should still use tile-sized tiles in this case (this will also prevent us from falling into gigantic tiles for WebKit2 find-in-page, among other things).
