Thanks but the recommendation is to have an aria-label if there's no content, not on every button/a element. Can you update the PR so that it only covers empty elements?

Thanks @Rich-Harris! I've updated it to cover this. I've also made a small tweak to ignore elements if they contain aria-hidden=true.

thanks!
