'preview' property from ui-admincentral's import dialog field 'name' causes node2bean problem

The Definitions app has revealed problems caused by the preview property in /modules/ui-admincentral/dialogs/import/form/tabs/import/fields/name@preview

The property seems to not be used at all, and is not coming from a previous version of the info.magnolia.ui.form.field.definition.BasicUploadFieldDefinition either . The error is then echoed in UI (importZip), Content Translation Support, DAM and JCR Tools because they all extend that dialog.
