Move status update to start on first focus, not on page load
Add the high-contrast focus indicator back (not sure when that got removed?)
Add aria-selected attributes to makeChoice, remove on clearValue
check arrow navigation works in all screen readers
** problems in JAWS/Chrome during filtered state
** Talkback/Chrome/Android not working well
** NVDA/Firefox seems ok, continue testing
Questions
What would the impact be of removing aria-controls attribute? It causes older JAWS to give additional instructions which are inaccurate.
Or should there be instructions at all? Excess instructions are usually annoying. On the other hand it's a custom widget, so people might not have encountered an input like it before.
