this is in a comment block indicating that it's a RenderWidget override, but I
don't see this function in RenderWidget.  Did you intend to put this in the
WebWidgetClient overrides section?  If so drop the OVERRIDE annotation - we
don't use that when implementing WebKit API defined in the WebKit repo.

Even better would be to implement a function on RenderWidget and call that
explicitly from RenderWidgetCompositor instead of bouncing through WebKit API

Done.
