Pagination label does not adjust correctly as categories are added and deleted from list

Description:

While adding and deleting categories from the Settings > Categories and Phrases list screen, the pagination label does not adjust as expected when going from 1 to 2 pages or 2 to 1 page. The page left/right buttons will disable and enable as expected, but the "Page X of Y" label does not.

Some of this behavior may be related to the root cause of bug #381 . So, depending on which issue is fixed first, the other may need to be re-tested after, to try and reproduce.

Steps To Reproduce:

1. Navigate to Settings > Categories and Phrases
2. Delete categories until there is only one page to display; note the behavior of the pagination label
3. Add a new category(ies) to the list so that there are now two pages.
4. On a tablet, you may need to reverse the order of steps 2 and 3 (add categories first, deleting categories second)

Expected behavior
As the number of categories adjusts so that the number of pages adjust from 1 to 2 and 2 to 1 , the pagination label displays "Page 1 of 2" and "Page 1 of 1" accordingly.

Actual Behavior
-> When deleting categories, once there is only one page to display the pagination label will display "Page 1 of 2" and then disappear.
-> When adding categories, the pagination label will not appear (remain missing) as the number of pages grows from 1 to 2.

Devices:

• Pixel 5 phone and Nexus 10 tablet (both emulated)
• Android 12 (both devices)

Screenshots

Start by reproducing the issue on the Settings > Categories and Phrases list with the Android 12 phone or tablet scenarios described. Trace where the pagination label updates as categories move between one and two pages; done means it shows "Page 1 of 2" and "Page 1 of 1" correctly after additions and deletions.
