Cisco-IOS-XE-native.yang produces incomplete vlan information when using list and add list

[rhasti]

Environment Cisco IOS XE Software, Version 17.06.03
using restconf with 'application/yang-data+json' calling Cisco-IOS-XE-native:native/interface

Config Snippet

interface GigabitEthernet1/0/34
description ESXI - VM-LAN - esxi-trz-10 - lan2/vmnic1
switchport trunk allowed vlan 11,12,14,15,22,23,101,168,169,171-173,175
switchport trunk allowed vlan add 300-302,666,2010-2012
switchport mode trunk
mtu 9198
spanning-tree portfast
spanning-tree guard root
hold-queue 4000 out
end

is producing following output

{'name': 'GigabitEthernetGigabitEthernet1/0/34',
 'description': 'ESXI - VM-LAN - esxi-trz-10 - lan2/vmnic1',
 'switchport-config': {'switchport': {'Cisco-IOS-XE-switch:mode': {'trunk': {}},
   'Cisco-IOS-XE-switch:trunk': {'allowed': {'vlan': {'add': '300-302,666,2010-2012'}}}}},
 'hold-queue': [{'direction': 'out', 'queue-length': 4000}],
 'mtu': 9198,
 'Cisco-IOS-XE-spanning-tree:spanning-tree': {'guard': 'root', 'portfast': {}}}

which is missing vlans 11,12,14,15,22,23,101,168,169,171-173,175
