Log Message:
-----------
Rare crash in RemoteLayerTreeDrawingAreaProxyMac::commitTransientZoom()
https://bugs.webkit.org/show_bug.cgi?id=288858
rdar://138515249
Reviewed by Abrar Rahman Protyasha.
Crash data suggest that `scrollingCoordinatorProxy()->rootScrollingNodeID()`
can return a std::nullopt
sometimes (i.e. no root node). The rootScrollingNodeID was only used for the
testing-only
`deferWheelEventTestCompletionForReason` code path, so we can just skip that.
