Ok I feel like I\'m crazy...
I\'m looking at Mobile Safari on iOs 6.0. I can\'t seem to establish any rhyme or reason as to when tapping on an element will trigger
I had this same issue. The simplest solution is not to bind the 'mouseenter' event on iOS (or any touch enabled target platform). If that is not bound the hover event won't get triggered and click is triggered on the first tap.
