I have following content structure:

Home

• Folder 1
  • Folder 1.1
    • Artikel 1
    • Artikel 2

Initially all contents are visible.
Now I hide "Folder 1.1" via "Hide"-Button in right content menu. The object "Folder 1.1" gets is_hidden flag in ezcontentobject table and is_invisible for the location. The child locations also get is_invisible flag in ezcontentobject_tree table. Everything correct so far.

After moving the hidden "Folder 1.1" to "Home" the is_invisible flag for all moved contents are set to 0 in ezcontentobject_tree, which is not correct in my opinion.
