Item count above table cuts off commas when updated via JS

[cbirdsong]

Bug Report

Expected Behavior

The item count should accurately reflect how many records are in Stream after it is updated with Javascript.

Actual Behavior

The item count is cut off at the first¹ comma when it is updated with Javascript.

Steps to Reproduce the Problem

1. Open the main Stream page (/wp-admin/admin.php?page=wp_stream) on a site with more than 999 items
2. Look at the number next to the pagination buttons. (ex.: 21,403 items)
3. Wait for something to happen elsewhere on the site that creates a record and updates the table.
4. Look at the number again. It will be quite a bit smaller than it was in step 2.

Screenshots

Footnotes

1. I guess technically I don't know if it is the first or second comma since I don't have a site with 1,000,000 records handy. 🙃 ↩

2. Both of these show exactly 165 pages, so I just double checked to verify that there is not also a problem with the "page X of Y" count. That number is working as expected on other sites, and these both being 165 is a ridiculous coincidence. ↩
