Now the Select2 instance is correctly recognized as a combobox, and the selected option is read aloud when it is focused, just like in a standard select box. This works by generating semi-random ids that are used for the ARIA attributes. These are not intended to be consistent by any means, they are just generated to make the instance accessible by screen readers.
