When live range selection is enabled, we hit the following assertion in 5 editing tests:

SHOULD NEVER BE REACHED
editing/FrameSelection.cpp(374) : bool WebCore::FrameSelection::setSelectionWithoutUpdatingAppearance(const WebCore::VisibleSelection &, OptionSet<WebCore::FrameSelection::SetSelectionOption>, WebCore::FrameSelection::CursorAlignOnScroll, WebCore::TextGranularity)
1   0x7b4271bf9 WTFCrash
