When installing a PWA, check whether URL and title match and warn the the user otherwise.
For most PWAs, the title is simply the apex domain without the TLD with some kind of capitalization. There are a few slightly more complex cases, such as Google Maps (google.com/maps) and YouTube Music (music.youtube.com). Even in these cases, there is an obvious relationship between URL and title.
Perhaps the PWA forces an overlay of the real apex domain at the top or in a top corner?
