From what I can see in your video, this looks like a bug. I’ll have to investigate this one some more and see about getting a fix in an upcoming beta. It should “just work”, but isn’t for some reason 
The Visibility setting in Elements is setting the visibility CSS property.
The block utility classes in Tailwind sets the display CSS property.
So I believe you might be confusing those two properties.
We don’t have a setting for the display CSS property in Elements due to various technical and/or user experience reasons.
Hope that clears things up!
