Wait - why does test_runner call this on the WebFrame while this gets the
WebView, then WebSettings? If you have a convenience function on WebFrame, use
that here.

This doesn't have a WebFrame AFAIK. Am I missing something?

   // APIs that compute the bounds of a range of text, it's a waste to
   // include these in the AX tree.
