After some reading about accessibility I would like to recommend removing aria-hidden=true, because it is meant for elements with multiple states (like collapsing items).

If we want to hide forever it seems that display: none; is sufficient. Maybe we could add hidden as this has good support in modern browsers:

But it seems that this is necessary to hide content from screen readers:

Can you confirm @00travelgirl00 ?
