Due to the new [horrible!] dropdown namespace selector [boooo], it's no longer possible to move (sub)pages across namespace.
Steps to reproduce (I guess):
- Create N:A e N:A/B
- Click move and select "M" in namespace dropdown
- Choose to move subpages
Expected result: N:A is moved to M:A and N:A/B to M:A/B.
Actual result: N:A/B is left behind and you're told that moving is impossible.
Example: see URL (last five moves were done by hand).
(Can we just drop this buggy dropdown selector that was introduced for no reason?)
