[Lazarus] Radiogroup not updating clicked button when in non-visible TPageControl tab

[Anthony Tekatch]

Hello,

I have a RadioGroup located on a PageControl tab that is sometimes made
invisible. If I update that RadioGroup ItemIndex programmatically when
that tab is invisible, then later make the tab visible and click on a
previously clicked (but not selected) radio button ... there is no
OnSelectionChanged (and also OnClick) event produced.

I submitted bug 0026714 which includes a test application:
  http://bugs.freepascal.org/view.php?id=26714

I am wondering if there is a simple workaround for this behavior, or is it
an actual bug?

Thanks,
Anthony
