Moving a document can rename a document without using configured StringCodec

In our project we have a custom StringCodec for translating document/folder names to lowercase. I noticed that when I moved a document, I was still able to move it to a destination document with a capitalized document name, e.g. a document "copyright" can be moved to "Copyright". That means our custom StringCodec was not used in the rename action.
Suggestion: remove the "Move document to .." input box in the Move dialog.
