Example: Close popup on mouse click without assigning new lens position

Clicking in the main renderer window passes a new position to the lens,
disregarding the "What's This" (documentation) overlay window.
This change checks if the documentation window is open on click, and if
it is, closes the documentation window and returns without further
handling of the mouse event.

Fixes: QTBUG-7205
