      Description

      When to concurrent updates attempt to remove different elements from a list, one of the updates may be lost.

      This happens for instance when concurrently removing proxies to the same document, which needs to update the ecm:proxyIds of the document (NXP-30001).

      To solve this, improve the diff analysis of lists and detect the case where one element is removed, then use the MongoDB $pullAll operation.
