When we added context support for fieldgroups, the assetname wasn't taken care of properly and thus ACL inheritance broke.
Testing Instructions
Create some fieldgroups and assign some fields to it.
Play with ACL settings. Settings should inherit from the component to fieldsgroups to fields. That means for example if you allow or deny the "Edit Custom Field Value" action in a field group, the fields in it should take that permission.

Tested permission inheritance from Component -> Field Group -> Field
