 >  The only small change there is to do `sidebars.sortable( 'refresh' );`
 instead of `$( this ).sortable( 'refresh' );` so when dragging over a
 closed sidebar to another closed sidebar, the second one is always
 refreshed too.

 Is that really necessary though? Couldn't the refresh be outside the has
 class "closed" so it fires on any over?
