Moving folders does not work

[handkerchief333]

Steps to reproduce

1. Create at least two folders FolderA and FolderB in a mail box/account
2. Move FolderA into FolderB per drag & drop or, select the three dots-menu of the folder FolderA, select "Postfach verschieben" (DE) and choose FolderB.

Expected behavior

FolderA should be a subfolder of FolderB

Actual behavior

FolderA stays outside of FolderB.

If FolderA and FolderB are at the beginning already in the same subfolder FolderC, and you try to move FolderA in FolderB, FolderA appears not in FolderB, but now at the same level as FolderC.

Thank you @GretaD for the fast response.

I tested again, you are right, it is working, but only on the first level.

Scenario:
Create this structure:

• FolderA
  • FolderC
• FolderB

-> Now move FolderC into FolderB without drag&drop.

Result: FolderC appears now outside of both FolderA/FolderB on the first level.

And after the previous step:
-> Move FolderC from the first level into FolderA or FolderB. Make a page reload

Result: FolderC appears still on the first level.

Same happens for nested folders with more levels than just two.
