Why/when do I have to tap twice to trigger click on iOS

Question

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

Answer 1

I was having this issue using Bootstrap, and I found out that the culprit was the tooltip. Remove the tooltip from the button and you don't need to tap it twice anymore.
