connected meta won't accept nested name for array

[Pollux321]

I need to query by two different connected meta values and then orderby one. In order to do that I need to give specific names to the nested queries which works regularly with meta_query but won't in this instance.

So in it's basic form with using orderby, this does not work

` 'connected_meta' => array(
'relation' => 'AND',
'level_meta' => array(
'key' => 'level',
'value' => '2',
'compare' => '=',
'type' => 'numeric',
),
'position_meta' => array(
'key' => 'list_position',
'value' => '1',
'compare' => '=',
'type' => 'numeric',
),
),

It does however work if I remove the array names.`
