### Configuration

Blink version: commit df04676bc07fde94b57a9cc7aedf2430ab996e07
iOS version: 17.3.1

### Describe the bug

When modifying an existing custom press with a hex code or custom string action, if I change the action to the other, go back and focus on the text field, the action type is reset to the original.

Expected behavior: action type is what I have set when I focus on the input.
