The WUA only ignores superseded updates when the superseding update IS APPROVED.
If the superseding update is Not Approved (or Expired/Declined, etc.), then the WUA will continue to evaluate and respond to the newest available update in the chain.
All you need to do is approve the most recent superseded update, and it will be installed.
When the newest update (e.g. KB2949927) is replaced, you can approve it and it will deploy.
