Form title resets to initial value upon invalid title name change

[foochifa]

Describe the bug
Form title will reset to original (title at page refresh) after an invalid title (e.g. less than 4 characters) have been inputted into the field.
Edit: Backend is updated, for the example below, upon refresh of page the correct title 'special' will be displayed.

To Reproduce
Steps to reproduce the behavior:

1. Go to any created forms
2. Go to Settings
3. Change form title to some valid title
4. Click out, see 'title saved' prompt
5. Change form title to an invalid title
6. Click out, form title resets to original title (title from pt 3 is not reflected)

Expected behavior
Form title should revert to latest saved title instead of the original title.
