When loading object references it will be answered with a bad request if onlyActiveObjCookie is set to false. Apparently a wrong pipeline stage is set.
Occurs in the backend or via Rest as HTTP 400 BADREQUEST error. In the frontend on the object view page in the footer. The table is stuck in loading mode.
I don't think it's extremely critical. At the moment nothing breaks in the frontend, but the references remain in an idle. Might bring an error handling in there in the same move.
I would like to make this "validate cookie in backend" nonsense in the step straight away.
