Just tried. If you're already streaming, it manages to show you the prompt, but there's no way to interact with it. The mouse moves (both on the host and client), but clicks don't go through. Keyboard navigation doesn't work either. If you try to stream something that first pops up UAC, the client just sits there waiting for it to be dealt with on the host.
