Create a new window, Add a chart with (eg. Bar) Series.
Set bottom margin to 0 (just for testing)
Go to data pane, edit labels of series
enter aaaaa -> everything is OK

enter ABCIIIIIIIIIIIIIIIIIII -> After entering a lot of I's, the A drops of the chart pane.

There are more character combinations that make it go wrong. used testing font is Arial 8 (the default)

Please fix, I have to set margins now which ends up short labels taking a lot of space.

(Still Using 7.11 - I can't find a changes doc for 7.12)
