Proposal

Add breakpoints for visually-hidden class

Motivation and context

We regularly use visually-hidden to hide text in icon-only buttons. On larger devices we sometimes want to show the text since there is enough available space.

We cannot determine a clean way to achieve this effect without adding breakpoint-specific classes or duplicating elements to use display classes (which poses accessibility-UX issues).
