Description

After creating a topic such as prefix-suffix and saving (on any repo), it becomes impossible to create a new topic named simply prefix because Gitea forces completion to prefix-suffix.

one hotfix/workaround: add prefix first, then add prefix-suffix

i will take a look on the problem

Testing this, it isn't impossible to create the "prefix" tab, but the behavior of the suggestions dropdown is bad:

• It auto selects the first suggestion when it shouldn't select any (just display them)
• It actually returns the selection on hitting escape instead of closing the suggestions

A work around (if anybody else sees) is to first use the up arrow to unselect the suggestion and then you can type prefix and hit enter as normal.

thanks for the note about escape key behavior

PR should fix both
