iControl get_static_route_destination inconsistency

On get_static_route_destination on urn iControl:Networking/RouteTableV2 there is missing info regarding route domain on default gateway objects. Works fine on nondefault static routes.

For example:

root@(f5-test)(cfg-sync Standalone)(Active)(/Common)(tmos) list net route VLAN_99 
net route VLAN_99 { 
gw 192.168.254.214%834 
network default%99 
} 

iControl req:

<soapenv:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mon="urn:iControl:Networking/RouteTableV2" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ins0="urn:iControl"> 
<soapenv:Body> 
<mon:get_static_route_destination> 
<routes> 
<item>/Common/VLAN_99</item> 
</routes> 
</mon:get_static_route_destination> 
</soapenv:Body> 
</soapenv:Envelope>

iControl response:

<E:Envelope xmlns:E="http://schemas.xmlsoap.org/soap/envelope/" xmlns:A="http://schemas.xmlsoap.org/soap/encoding/" xmlns:s="http://www.w3.org/2001/XMLSchema-instance" xmlns:y="http://www.w3.org/2001/XMLSchema" xmlns:iControl="urn:iControl" E:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">

So, is there a wy to get info regarding netwrok route domain of default route? On nondefault route iControl returns route domain in address element of response, so I'd expect it to behave the same with default route.

Thank you
