Comment 12 for bug 1869898

Rebased branch:

https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/berick/lp1869898-ang-staff-cat-default-5

No changes were required for Ang10.

I suggest we also merge bug #1889694 and bug #1889685, which I have marked as blockers, when this branch is merged. I can create a combo branch if it helps.
