Hi,
I think we're not looking at the same website or you have some caching issue on your local network.
Here is what I see on your website with the user account you provided on the URL you provided:

And here is what I see before I'm logged in:

You can see the URL of the website / page I'm using for my tests at the top of the screenshots.
Also, note the look of the icons on my screenshots. They all display as little squares. This is typical of a problem with the font awesome library on a Joomla website. Usually it comes from a setting in the template.
However, I'm surprised you don't have the issue on your end.
Similarly, look at the "LIVE" status label. On my end it take the whole width. That's the expected default behavior without custom CSS.
However, on your new video, I can see it only takes a bit more than the width of the label.
I think that all of this, as well as the fact that I can't reproduce the issue anymore on your website and you can is linked.
You might have some kind of caching proxy or something on your network preventing you from getting the updated CSS / JS I've added and present on your website and you're stuck with the old version in the cache of the proxy, which doesn't have the fixes and changes. And same for font-awesome. You must have the issue on your website, but you don't see it because of the proxy cache.
That, or we're actually looking at two copies of the website, me on the latest copy, you, a copy from before the patches.
