CSS: Don't workaround the IE 11 iframe-in-fullscreen sizing issues

mgol · mgol · commit ff1a0822f72d · 2016-04-26T21:19:54.000+02:00
IE 11 used to have an issue where if an element inside an iframe was put in fullscreen mode, the element dimensions started being 100 times too small; we've added a workaround that would multiply them by 100. However, the IE 11 issue has been unexpectedly fixed and since our detection was really detecting the browser and not a bug, we've started breaking the browser instead of fixing it. Since there's no good way to detect if the bug exists, we have to back the workaround out completely. Fixes gh-3041 Refs gh-1764 Refs gh-2401 Refs 90d828b
