Should values shown in browser update automatically?

Can someone clear up something for me please? Using 1.8.2 classicui if I have Text fields in a sitemap where the item values are updated in the background (via mqtt in my case but that should not be significant) should they automatically update in the browser window without having to refresh the page?

If so I would be grateful to see a copy/paste of the contents of the request log showing the requests that get the update.

It seems I was being confused by this bug
