[ThreadedCompositor] Scrolling artifacts on accelerated subframes
https://bugs.webkit.org/show_bug.cgi?id=149060
Reviewed by Michael Catanzaro.
The problem is that we are scrolling the main frame even when scrolling is not delegated.
* WebProcess/WebPage/CoordinatedGraphics/ThreadedCoordinatedLayerTreeHost.cpp:
(WebKit::ThreadedCoordinatedLayerTreeHost::scrollNonCompositedContents): Return early if main frame view doesn't
delegate scrolling.
