Summary:
World names cannot be edited if the name is very long and the world is copied.

Steps to Reproduce:

1. Rename World with very long name (at least 24 characters in enUS version).
2. Enter Settings of the World.
3. Create a copy of previously created World.
4. Attempt to change World Name of the World created in step 3.
5. Observe the issue.

Observed Results:
World Name cannot be edited if it contains too many characters (exceeds max number that Player can put inside the text box).

Issue occurs after 'Copy of' string is added to World Name and it exceeds the max number of characters after the change. Issue also occurs after downloading a World from Realm with very long name.

User can fix this issue by selecting the text by pressing CTRL + A and deleting World Name.

Expected Results:
Player should always be able to change the World Name.
