Add integration test for "type" prop changes

# What

Need to add integration test for the change of the 'type" prop of a field.

# Why

The "type" prop has a subscription that reflects its changes in a field's state. This must be tested.

# How

- [ ] Make sure the subscription works with the new event handling system
- [ ] Create an integration test that toggles a field's "type", and assert the type in the state
