--- Comment #7 from Daniel Bates <dbates at webkit.org> ---
Taking this bug back.... WebKit does not consider the fact that causing the keyboard to show or hide as a result of an HTML inputmode change can effect the position of touchevents (and mouse events) that are being processed. More specifically, the bug on slides.google.com occurs because the UI process is notified of the HTML inputMode change and we reload the input views between the touchdown and touchup as debug logging shows:

### -_webTouchEventsRecognized:; type: TouchStart
### -_webTouchEventsRecognized:; type: TouchEnd
### -_webTouchEventsRecognized:; type: TouchStart
### -_didUpdateInputMode:
### -_keyboardWillShow:
### -_webTouchEventsRecognized:; type: TouchEnd
### -_keyboardDidShow:

My guess is that Google changes focus on touchup (aka TouchEnd) and the showing of the keyboard effects the tapped point on the page.
