Bugfest: Inventory. Sorting by Title gives different result counts than no sort when *searching*

Steps to reproduce:

1. Login to FOLIO BugFest,
2. Clear cache for page by clicking ctrl F5 in Windows or Command + Shift + R on a Mac
3. Go to Inventory
4. Select the Instance segment in the Search and filter pane
5. Search in the search box on Keyword (title, contributor, identifier) on: Jensen (I saw this problem when doing other searches, as well (e.g. Contributor)
   1. Notice that the results are sorted by Title by default (despite
   2. "2,508 records found" is displayed
6. Switch to the Holdings segment and select "Keyword (title, contributor, identifier), and search on: Jensen
   1. Notice that the results are NOT sorted by Title by default
   2. "7,955 records found" is displayed
7. Switch to the Item segment and select "Keyword (title, contributor, identifier), and search on: Jensen
   1. Notice that the results are NOT sorted by Title by default
   2. "7,955 records found" is displayed
8. Switch then back again Instance segment, click "reset all" and select "Keyword (title, contributor, identifier), and search on: Jensen
   1. Results are no longer sorted by Title by default (the only way I can get this default sort to happen again is to clear the cache)
   2. "7,955 records found" is displayed
9. Now, click the Title column header to manually sort by Title
10. Notice that the result count changes to "2,508 records found"
11. Now click "Reset all" and switch to Contributor search
12. Search for Jensen
13. Notice that, also when searching contributors by Jensen, sorting by Title gives different result counts (presumably this happens for many types of searches)

Expected Result:

• Sorting by Title (or any other column) should not change the result count

Actual Result:

• When sorted by title (either by default the first time after cache cleared or manually by clicking the column header), the result count that displays changes (in some cases considerably)

Additional Info:

• Sorting by other columns doesn't change the results count
• We have another issue wherein sorting by title gives different result counts when applying filters: UIIN-1071
• Testing this in BugFest resulted in instability and crashes over time:
  • For example, this "bad gateway" error
    
  • And this error:
    
  • And sometimes clicking Inventory just resulted in a blank page
