Multiple instances of a Form fragment on a form - input data replicated in each instance
We have an address fragment that we have pulled in twice to a form (address and work address) When we enter the postcode in the 1st instance the postcode field the second instance field renders the same value. We have tried this with and without a schema for the form. Where we have used a schema we have bound each fragment to the specific part of the data model.

When it rendered and you enter data its it repeated in the field for the other fragment

The generated input fields have different id and name attributes.
Does anyone know if there is a mechanism to address this?
