No, you should need to explicitly hide() it or delete it. But if you use
Dialog::run(), run() will return when one of the buttons is pressed.
Maybe the dialog is just going out of scope when Dialog::run() returns.

I think you can override on_response() to prevent run() from returning.
I forget the details.
