/admin/config/emoji non responsive/locks up

when using a fresh development environment following the steps here:

when you go to /admin/config/emoji clicking on “Settings” “Add emoji” does not load the pages, this requires a page refresh after clicking the links.

With the page refreshed Settings shows and Add Emoji shows.

When you add your first emoji it redirects to /admin/config/emoji and you cannot see the emoji just added, you have to refresh the page.

Once refreshed you can see your first emoji uploaded.

When you try to upload a second or any additional emojis even refreshing the /admin/config/emoji page no emojis are shown so you can no longer manage uploaded emojis even though they usable throughout the website.
