    Description

      Queries using scan consistency (request_plus) on collections will never get to the required DCP state if a vbucket has its latest sequence number advanced due to a system event (e.g. some collection created/dropped).
      To reproduce:
      1. Create a bucket, scope, and a collection c1.
      2. Insert a single record in c1.
      3. Create Analytics collection on c1.
      4. Run scan consistency query (request_plus) on c1.
      The query will wait indefinitely if no scan_wait is specified.
