Description

Issue: In form builder mode, when a select component with a URL data source and a default value is saved, it stores selectData. After saving, the select component also saves global metadata for this component. Consequently, any further changes to the default value will use the select data from the metadata instead of the new select component configuration.

Solution: Reset the submission value for the webform in the form builder during the rebuild process. This ensures that the metadata is empty, allowing the select component to reassign it with the new component configuration and show the correct component preview.
