Hi, this is what I manage to reproduced just now. I removed the tabpanel and start it over.
The name of the form in the tabpanel is flight_tower_departure, which initially goes out of the form's boundaries.

If I move the tabpanel to the left the warning dissapear.

If I change the name of the tab to a shorter one and place the tabpanel where I need it, the warning appears again.

So it seems that it counts the bounds of the tab inside the tabpanel using its form name, instead of the name or text of the tab.
