-// Future-proof rule: in browsers that support :focus-visible, suppress the focus outline
-// on elements that programmatically receive focus but wouldn't normally show a visible
-// focus outline. In general, this would mean that the outline is only applied if the
-// interaction that led to the element receiving programmatic focus was a keyboard interaction,
-// or the browser has somehow determined that the user is primarily a keyboard user and/or
-// wants focus outlines to always be presented.
