When adding 3rd party repos via link https gets duplicated

• Device OS and version: Android 13 AOSP, Lineage based
• Device model/manufacturer: Xiaomi MI 9T
• F-Droid version (in the About screen): 1.16-alpha2
• F-Droid privileged extension version (if installed): -

What did you do? (clear steps if possible)

I wanted to add the Kvaesito repository to my repo list by having this link on clipboard:

https://raw.githubusercontent.com/MM2-0/fdroid/main/fdroid/repo/?fingerprint=156FBAB952F6996415F198F3F29628D24B30E725B0F07A2B49C3A9B5161EEE1A

As expected F-Droid filled in the URL and fingerprint fields accordingly however when I hit Add, the final repository added seems to have https:// doubled. If I try to add the repo without the https:// at the beginning it complains that the URL is not in the right format.

With the doubled https:// it cannot fetch the repo either.

What did you expect to see?

The right URL and that the manual update trigger from the home page succeeds.

What did you see instead?

Doubled https:// before the link and errors on fetching the updates.

PS: It seems to be fine on stable.
