Bug 1486514 [wpt PR 12695] - Make reftests 800x600 everywhere, a=testonly Automatic update from web-platform-tests Change reftest size to 800x600 everywhere (#12695) With Firefox, with the internal reftest runner (used by default), this doesn't actually change the reftest size in Firefox versions prior to 66 (currently on the beta channel); to get the correct behaviour with older versions of Firefox, you must pass `--reftest-external` to use the external reftest runner. -- wpt-commits: d5f07ed3b5186e553940a3d5c547067850a4e3f0 wpt-pr: 12695
