JSONForm placed in modal does not update default value from source data

Editor assessment

The subject states the defect exactly: a JSONForm placed inside a modal did not update its default value from source data. The component, the placement condition, and the failing behavior are all named, which is everything a reader needs. The fix type matches. No scope is present, though the form area is identified. There is no body, acceptable for a compact defect fix whose headline contains the complete failure scenario. No footers appear. The message is precise, honest, and fully self-sufficient without the diff.
