accordion group inconsistent callback value

Trying to work with an accordion group in controlled mode but having issues getting the right value on the `onExpandedChange` callback.

https://stackblitz.com/edit/nextjs-hu1mpy?file=app%2Fpage.tsx

If i click on Accordion 1 then Accordion 2 then Accordion 1 then Accordion 2
i should expect to always have `expanded = true` in the `onExpandedChange` callback right?

right now it would show `true, true, false, false`

is this the expected behaviour ?

Thanks
