Is this work supposed to be associated only with the WebView? It seems like it
should probably be associated with the WebFrameWidget, to match how the other
IME stuff works.

(We could/should even move this to a private section, since this is a new
method)

   void resetInputMethod() override {}
   WebScreenInfo screenInfo() override { return WebScreenInfo(); }
   void setTouchAction(WebTouchAction touchAction) override {}
