The need to do a hit test to re-find the element is probably expensive and
possibly flaky. RenderFrameImpl::context_menu_node_ stores the WebNode that
spawned the context menu. Perhaps, when the menu closes, we could use that to
find the right element?

You you point me to the code for this? This follows the path of the save image
and copy image context menu options.
