it seems weird to infer this type based on the override-redirect-ness of the
browser. is there some other way to detect this?

Well, given that TYPE_DRAG_BROWSER is exactly TYPE_BROWSER, but with the
difference of using an undecorated frame (override-redirect), I think it’s
appropriate.

How do you suggest to solve your concern? To me, it seems like renaming either
of the two properties might be a good solution. I’m willing to do that, but I
don’t have a good suggestion. What are your thoughts?
