Comment 1 for bug 1755502

It suddenly occurred to me that this bug could have also been caused by the new copy alert work.

I did some additional testing to see if I could pinpoint the cause of the problem. After reverting the code that was added for the holds pickup work on bug 1661688, I found that the "Item On Hold Shelf" alert only displayed when checking out to somebody who is not the holds patron, as is the expected behavior.
