Event: Update support comments for mouseenter/mouseleave implementation

mgol · mgol · commit d176001e6e4f · 2015-07-27T22:30:19.000+02:00
Custom mouseenter/mouseleave implementation was needed because of: 1. Safari 6 not implementing mouseenter/mouseleave at all. 2. Chrome sending mouseenter too often. The second issue has been fixed in Chrome but exists now in Safari 7 (it's fixed in Safari 8) so we have to keep it for now, unfortunately. (cherry-picked from 2792845)
