Tool Tip, Right Click Thumbnail renders at top location when Panel is moved to bottom

[moreChalk]

Steps to recreate:

1. babar setting -- Move panel to bottom of the screen: True
2. babar setting -- Tasks: right click to show window thumbnail: True
3. Right click on active window

I was expecting the thumbnail to render relative to the bottom position the bar is now located at. Instead both the roll-overview tool tip and the preview continue to render as if the bar remained on the top. Unsure if this would be considered a bug or feature.
