Scrollable listbox review

James and Siri, Could you please test the scrollable listbox example and
comment in issue 469?

https://github.com/w3c/aria-practices/issues/469

 

Of course, the more people that test and review, the better. 

 

I'll be merging some more changes to the rearrangeable listbox page soon.
Then, it will be ready as well.

 

Thanks,

Matt
