Having the label passed in to the application role is much nicer because it gives the application a label that is also discoverable via browse mode navigation.

@MarcoZehe Am I going to get in trouble with the ARIA spec by removing the aria-label from the treegrid role? Seems like in this situation since we've got a dedicated application here, it should be fine.

<table
{ ...props }
role="treegrid"
onKeyDown={ onKeyDown }

<tbody>{ children }</tbody>
</table>
</div>
