Tested the latest Steam version kindly provided by cheswick of /r/ultrawidemasterrace at 2560x1080, 3840x1080 and 5760x1080, although the UI spanning would be very inconvenient at the latter. Please let me know whether this works in the Microsoft Store version, or tell me the process name for it.
You can buy me a coffee here.
