Also, it seems that with most // browsers, the target of the mouse/click event is not calculated until the // time it is dispatched, so if you replace an element that you touched // with another element, the target of the mouse/click will be the new // element underneath that point. // // Aside from proximity, we also check to see if the target and any // of its ancestors were the ones that blocked a click. This is necessary // because of the strange mouse/click target calculation done in the // Android 2.1 browser, where if you click on an element, and there is a // mouse/click handler on one of its ancestors, the target will be the // innermost child of the touched element, even if that child is no where // near the point of touch.
