### What happened

If you completely delete all of the text from a model name, you will be unable to save any new name irrespective of how much or what text you go on to enter. If you get into this state, you must cancel the edit, and then click edit again.

If you leave at least four characters in the field, you can add additional text and then successfully save the new name. This is despite the prompt appearing that names must be at least three characters. (i.e. if you delete all but three characters, you get the warning and are unable to save a new name).

### What you expected to happen

I expect to be able to rename models within the model manage as I see fit. The save button should remain greyed out only if text is missing from the field.

### How to reproduce the problem

1. Launch Invoke
2. Go into the model manager
3. Select a model
4. Click the EDIT button
5. Highlight and delete of all the text from the model name (you will get a warning that the name needs to be at least 3 characters)
6. Enter a new name of more than 4 characters (the name length warning will disappear)
7. The save button remains greyed out, you are unable to save the new name

### Additional context

I have this issue on both macOS and linux, I don't have a Windows device so cannot test there.
