Re: [EXTERNAL]Exposing the selected state of buttons

Whether one works better than the other (aria-selected vs aria-pressed),
make sure you understand which attribute is allowed based on the role of
the element.

As Patrick alluded to in the first response to this question last month, he
originally said aria-selected but then quickly fixed that to aria-pressed.
If you look at the table in the URL given above and navigate down to the
"button" row, you'll see aria-expanded and aria-pressed (in addition to
global ARIA attributes) are the only ones allowed on a button.

As far as which browser/screen reader combinations it works on, absolutely
follow Birkir's advice and file issues if it doesn't work.
