Pager not updating on last click

Problem/Motivation

Count updates until the final Load more click, then the previous value count remains

Proposed resolution

Pass pager values into drupalSettings, and replace count div. This is very much a proof of concept, so I added a div with an id 'custom-pager-count' attribute to the global views result count - when the last page is reached, I'm replacing the text with `Displaying ${totalItems} of ${totalItems} items`
