New question. The popup's constructor sets WA_DeleteOnClose, but it's stack-allocated here. Is there anything guaranteeing we don't end up with a double-free?

I never encountered issues with this when testing but I did not manage to find a clear answer for this in Qt documentation so it's probably better to move the setAttribute outside of the constructor.
