Test file highlighting the problem

For regions that have overflow: hidden and are absolutely positioned, hit testing is broken, as follows:
  - :hover rules never get applied
  - mouse events handlers don't fire
  - document.elementFromPoint() returns bogus elements.

For instance, in the attached test file:
- the text below the regions should read "document.elementFromPoint() - OK"
- move the mouse over the orange rectangle and click

EXP: orange rectangle turns black, PASS appears
ACT: orange rectangle turns black, nothing appears
