Thanks, I think the NEWS entry should tell a bit more about the new
option.

@cindex could be more reader-friendly, e.g.

  @cindex @code{aria-hidden}, HTML attribute

The last sentence is incomplete, suggest to either make it part of the
previous one, or say something like "It can be useful even when not..."

Thanks.
