exception in idle callback considered unhandled

[basiliscos]

Hi,

when my idle callback is invoked, and there an exception is thrown, then I expected that App::OnExceptionInMainLoop() should be invoked instead of App:OnUnhandledException().

Here is a relevant backtrace of the last case:

Is the current behavior expected? I can't find that in docs, so I'd expected the common case for exceptions handling...

wxVersion: 3.2.6

I agree that this is wrong, and different from wxMSW. I've created #25315 which should fix it, please let me know if you still see any problems with it.

Thank you! Will test it with the next wx release !
