After choosing one of "Allow to Share Window" or "Allow to Share Screen" from the share screen permission dialog, user is unable to change or confirm the selection using a keyboard. This was attempted both with Keyboard Navigation turned on and off. Mouse hover selection and click confirmation of the target window/screen works. Tested against https://webrtc.github.io/samples/src/content/getusermedia/getdisplaymedia/.
