Loop to fill zone details does not work

	foreach( $zones as $zone ) {
	$zone = $this->_fill_zone_details( $zone );
	}

That assignment back to $zone is flawed, since the variable just gets overridden on the next loop iteration, and the original $zones (which is returned from the function) is never updated.

See https://3v4l.org/QMZl6 as a POC.

While the fix is easy, we'll need to see what the implications are for having the $zones now populated with more data.
