* frameModule.topmost() - now returns the last navigated Frame or
the currently selected tab item's Frame if the tab item's view is a
Frame.
* frameModule.getFrameById(id: string) - returns a navigated Frame by id.
* args.object.page.frame - can be used in page elements event handlers.
Returns the Frame of the current element's page.
