Comment (by gacar):

 We already had a test for screenX and screenY:
 https://gitweb.torproject.org/boklm/tor-browser-bundle-
 testsuite.git/blob/HEAD:/selenium-tests/test_fp_screen_coords.py#l11

 Do we need to test any additional behavior or just need to pass this test
 with ESR31 based TBB? I'd be happy to write a new test if former is the
 case.
