No on/off toggle for elements in responsive mode

The documentation says that in responsive mode, there should be an eye icon to hide/display elements in responsive mode, but I see no such icon.

I was made aware in a previous ticket regarding image captions that the documentation needs to up dated to reflect recent changes to the UF editor. So has the eye icon been replaced, am I looking in the wrong place, or is it bug with my install?

Please advise.
