Spike: Inventory Search Results Changing and Odd Page Display

Steps to repro:

1. Log into folio-snapshot
2. Go to Inventory
3. Instance search results are usually ordered by title with 14 Cows for America at the top
4. Pick an Instance
5. Drill down to view the item record
6. Not sure if this part is required for the repro steps, but this is what I did:
   1. Copy item barcode
   2. Go to requests
   3. Create a request for that item
7. Go back to inventory by clicking the Inventory icon in top nav
8. Close Item details overlay
9. Close instance details preview pane

Expected: Should see the search results I saw initially which showed 14 cows for america at the top and a full page of results

Actual: Shows search results with Interesting times at the top and only half the page is populated with search results.

This does repro consistently.
