Steps to reproduce

1.  Go to pages-app in demoauthor and select variant contact: americas /travel/contact/variants
2.  Click choose audience action

Expected results

In the traits section there is a default value for All as it was in previous versions. This would avoid having an empty value for op when more than one trait is picked up.

Actual results

No default value is selected

Development notes

Since it is a custom field (info.magnolia.personalization.ui.RuleOperandSelector.Definition) that is autogenerated, it is not possible to decorate the dialog to add the defaultValue property.

Tested also in 6.2.9-SNAPSHOT
