Comment (by afercia):

 No idea why, the CSS rule triggering this bug is the transform applied to
 the buttons when they're in an `:active` state, i.e. while they're
 "clicked". See `transform: translateY(1px);` in `buttons.css`.
 (just a wild guess: Firefox repaints the button and in combination with
 "something else" this makes NVDA think it's landed on a new element).

 The refreshed patch:
 - resets the CSS transform for this button
 - cleans up a CSS rule that as using a no more used selector
 - removes translatable strings that were introduced to test future
 improvements and not actually used in this patch

 `aria-expanded` is now announced correctly by al the major screen readers.
