Link to share an app doesn't respect the repo the app is in

• Device OS and version: all
• Device model/manufacturer: n/a
• F-Droid version (in the About screen): 1.7.1 (but happens with other versions, too)
• F-Droid privileged extension version (if installed): n/a (but in my case, yes)

What did you do? (clear steps if possible)

• pick an app from e.g. the IzzyOnDroid repo – say "PhoneProfilesPlus"
• hit the "share" button to share the link with some other app

What did you expect to see?

A link pointing to where the app is, in this example: https://apt.izzysoft.de/fdroid/index/apk/sk.henrichg.phoneprofilesplus

What did you see instead?

A link pointing to https://f-droid.org/app/sk.henrichg.phoneprofilesplus – which for obvious reasons gives a 404
