Title: Detection improvement: Find visible descendant of non-visible clickable.

Problem : Before, for a detected clickable element without visible
client rect, an attempt was made to see if a floated direct
child was visible. But this still missed some other cases
(when child is not direct but descendant, or when child is
not floated but positioned otherwise).
Solution: Now, detection recurses down until finding a visible client
rect, no matter how deep in the hierarchy or positioning
method used.
