Error whenever trying to edit a document with a JSON property. Again.

[chonymony]

Describe the bug
When trying to edit a document that contains a JSON as a property, sometimes at random a ""deleted_object_still_referenced" error still pops. This bug has been reported before but marked as complete but apparently it hasn't.

To Reproduce
Not exactly sure how to reproduce as this error appears randomly but it's with objects that contain at least one JSON as property.

Expected behavior
Be able to edit documents without the issue.

It's surging with the same type of document, and when "fixes" itself I noticed that it rolls back the changes or deletes partially the json of the property.
