Created an attachment (id=236383)

Repro -- bug-416058_Test14_ContainerControl.cs
Attached is a modified version of Jonathan's sample that shows the problem.
The crucial line is "ep.ContainerControl = this;". With it the icons are
apparently then incorrectly drawn relative to the form and not to each
control's parent (the tabpage).
MSDN says for the ContainerControl property:
Typically, this is the Form the data-bound controls reside on.
So should it be used *solely* for data-binding purposes
(ContainerControl.BindingContext etc), and be ignored completely for
painting/parenting/etc/etc?
It would explain why we've had problems with NRE bugs related to it! :-'(
