Given your accurate description it sounds plausible. You might find you 
can reproduce it in Firefox by loading two pages with titles on the body 
tag (so the whole page has a tooltip) in separate windows.

The problem might be platform-specific (sadly you don't reveal which 
platform(s) you use). If that's the case then it sounds like a core 
widget bug.

A workaround might be to check the window mediator to see if you were 
the most recent window before showing the tooltip.
