test case

Steps:
1. Open the attached HTML
2. click mouse somewhere to show the offset of mouse within the element
3. zoom the page *and* resize the window to make the page scroll
4. scroll the page horizontally and/or vertically, 
5. click mouse in the same place as step 2., observe the printed offset.

Results:
the printd offset is different when page is zoomed and scrolled.

Expected:
the printed offset should be the same.


Cause:
The real cause is the wrong calculation of event.clientX/Y when  page is zoomed and scrolled.
After Sam fixed the event.clientX/Y in r49551,  patch in r49490 ( for issue 30034) should be reverted.

NP. Instead, I should thank you for taking care of this, as always!
