duplicate wiki directories: cannot move page

~bug I think this is a bug. Could you have a look please?

Example Project

https://gitlab.com/CardBook/CardBook/wikis/home

wiki-duplicateentry-bug

I have only created one of the 2 "server-configuration" entries. The other one created itself erroneously when creating the "Synology" sub-entry.

The problem is that I cannot move the sub-entry ("Synology") to the other "server-configuration" directory.

steps to reproduce

  1. go to "Synology"
  2. edit page
  3. change title to server-configuration/synology or server configuration/synology

current bug behavior

page doesn't move

expected correct behavior

page should move
