What is the current behavior?

I have the form with FIeldArray component inside.

• "append customer" ie adding new element to array.
• click on the Set Field Data Here span -> it set the data: { disabled: true }(check in console after next step to ensure data is set) to the the element with 0 index
• then append a new one(index 1).
• click Set Field Data Here
• after that - click X to delete the element with index 0.

In console - check for the the the logging of the zero element(previous first one) -> data: {}.

What is the expected behavior?

In console - check for the the the logging of the zero element -> data: { disabled: true }.
