3.10 - Cannot add call numbers or items from item status

[Elaine Hardy]

3.10

In item status, attempting to add items and/or call numbers fails since the holdings editor tab doesn't open (browser is set to open tabs and other tabs open from item status)

Console error is

vendor.bundle.js:6 ReferenceError: hide_vols is not defined
    at item.js:754:31
    at l (vendor.bundle.js:6:69347)
    at vendor.bundle.js:6:69793

Also an issue in 3.9. Unable to test 3.8.

Marking Confirmed

[Katie Greenleaf Martin (kgmspark)]

This particularly affects our users who use a workflow of scanning a barcoded item (in most cases a magazine) in order to add a holding.
This does NOT appear to occur in 3.9.0 but DOES occur in 3.9.1.

[Susan Schirripa (bapl55)]

We also aren't able to delete items or create new marc records.

I was testing this during bug squashing week, and it seemed to be working again in 3.11 beta on the
https://tiffany-master.gapines.org server.

[Katie Greenleaf Martin (kgmspark)]

it does NOT work on https://butternut.evergreencatalog.com/ on the same day, so it must be a patch that is being tested on Tiffany/GAPines' server as opposed to being fixed in 3.11 in general?
