I've reported this upstream (although - being Gnome, I'm not expecting much other than a "we're right, you're wrong" response). (OT: Sad Unity is disappearing!)
Thanks for pointing out it can be overridden in the Tweak tool. I didn't think to look there. Actually, as it happens, "Windows" -> "Attach Modal Dialogues" was already turned off. I had to turn it _on_, then off again, before it took any effect. (Possibly a bug I guess, but I'm certainly a lot happier now this is adjusted).

This is a huge nuisance, in the case where I want to move the dialogue to uncover some text from the underlying document, to construct a save file name (e.g. matching title of document to filename etc..). It is really unexpected that dragging the title bar of an dialogue also moves the parent application.
