It depends which class was added last. This class will be selected. Umbrello
doesn't store any Z-axis information at all. During painting it doesn't look
at overlapping. It just paints a class and it may be that the next class
draws over this class.

I don't see any way to fix this bug. Of course we can add Z-axis information
to the widgets, but that would mean a major effort. And I think the gain is
really minor.

So I like to ask to close this bug with resolution "Won't fix".
