Browser: FF

Steps to reproduce:

1. Create a new Form, then open Form Builder
2. Drag and drop a couple of fields, let's say Single Line ones
3. Open fields' settings modal
4. Change the name, hit enter on the keyboard

Result:

The settings modal disappears, but the name of the field is not updated in the preview. It is properly saved though as you can notice after closing Form Builder.

Expected result:

The field name is updated accordingly.
