Pages > Alphabetical view shows "There are no pages starting with ''." when accessed by confluence-administrator user that doesn't have Space Permission

Steps to reproduce

• be logged in as a member of confluence-administrators group
• do not have the "view" permission on the space, neither directly nor through a group
• Anonymous do not have "view" permission on the space
• go to Space > Pages > Alphabetical and you'll get:

  There are no pages starting with ''.
  

  

• Space > Pages > Tree view and Space > Pages > Recently Updated shows fine due to CONF-20697

Although being a confluence-administrators user, if the user doesn't have Space view permission, all the 3 Pages view should not show anything even though the pages are still accessible by direct access.
