Window moving virtual desktop

Now (since F37, I think), clicking on a URL in an email (in Evolution, 3.46.3-1.fc37) moves my browser (FireFox) to the same virtual desktop that Evolution is in. It didn't used to do this, and it's not what I want, but I can see some might want that, so is it an option somewhere? If so, where?
