I don't understand why it would do that.. Maybe I am missing a piece of
the puzzle.
If this is a brand new application window, the workspace should be unset.

That's correct, and I'm not sure what can be done to change that. We
just aren't notified of anything by the window manager on the client.

I would have to test this for myself to know for sure, can you please
file a ticket so I don't forget?
