Tooltip m1 in ui window

Tooltip m1 in ui window

Hi ;)
Got a little "issue" while testing the new tooltip class for usage in our project:

if you're using it in a window and there's not enough space above to show the full tooltip, its "cut" a bit.. should be moved a bit down, the TT should not start out of the page :) (see Screenshot)

Any ideas how to solve it?

Regards
Simon
