Expected behavior:
When any windows from Sparkle are on the screen, they should be in the Window menu, so you can get back to them. Right now, you have to dig around moving windows manually to try find it again.
This is something you may encounter if you hit update, then switch back to do something before you update... Now the window is going to be pretty hard to find again.
I doubt it belongs in the tab groups menu, but it should at least be accessible from the OS-level window menu.
