I have been doing some research on specifically when the iPad fires "mouseover" events versus "click" events. When the user taps anywhere on the page the iPad first fires a "mouseover" event as though the user had just placed a mouse cursor on that spot. It also fires a "mouseout" event on the last element that had focus. The browser then, as far as I can tell, checks whether any changes to the DOM occurred as a result of "mouseover" event callback.

If there has been a change to the DOM the browser does not fire a "click" event. If the user taps on the same element a second time the browser does fire a "click" event but does not fire another "mouseover" event.

On the other hand, if after the user taps on an element for the first time and the DOM has not changed after the "mouseover" event completes, then the browser fires a "click" event without waiting for a second tap.
