Description Matt Woodrow 2023-04-04 10:33:59 PDT 
<rdar://104436838>

When scrolling Weather Channel weather.com — the blue background appears to have to catch up to the scrolling, no issue with UI-side disabled.

ThreadedScrollingTree::canUpdateLayersOnScrollingThread() returns false when scrolling weather.com, so we don’t do any async scrolling using the old code.
