Nested content-blocks compound validation adds violation message on all ancestors

When a content-block contains a nested content-block (e.g. Employee -> Interview) and the nested block (Interview) contains a compound field with a compound validator, the violation message is displayed on all ancestors.

Steps to reproduce:

• add hap:validationdatescompound to the compoundList property of /hippo:namespaces/hap/employee/editor:templates/default/interviews
• *in the validation document, add a new employee content block and than add a new *validationdatescompound in the Interview field
• press save

Expected: Message "The dates are not in sequence" is displayed in the validationdatescompound block

Actual: Message "The dates are not in sequence" is repeated on all ancestors of the validationdatescompound (as well as the red border)
