netplan routes config scope link take no effect

[nie ying ge]

my ubuntu os version： Ubuntu 18.04.2 LTS
netplan version：
ii netplan.io 0.40.1~18.04.4 amd64

my netplan config：
 cat /etc/netplan/01-netcfg.yaml
network:
  version: 2
  renderer: networkd
  ethernets:
    eno1:
      dhcp4: no
      addresses:
        - 10.10.56.110/21
      nameservers:
          addresses:
            - 10.10.0.1
      routing-policy:
        - from: 10.10.0.0/16
          to: 10.0.0.0/8
          table: 200
          priority: 10001
      routes:
        - to: 10.10.56.0/21
          scope: link
          via: 10.10.63.254
          table: 200
        - to: 0.0.0.0/0
          via: 10.10.63.254
          table: 200
        - to: 10.0.0.0/8
          via: 10.10.63.254

current route table 200：
ip route list table 200
default via 10.10.63.254 dev eno1 proto static

I think it shoud be：
ip route list table 200
default via 10.10.63.254 dev eno1 proto static
10.10.56.0/21 dev eno1 scope link

i know there has bug report of this:
https://bugs.launchpad.net/netplan/+bug/1747455
and i update my netplan to 0.96-0ubuntu0.18.04.4, i downloaded the deb file from https://launchpad.net/ubuntu/+source/netplan.io/0.96-0ubuntu0.18.04.4/+build/16713760/+files/netplan.io_0.96-0ubuntu0.18.04.4_amd64.deb

but it make no difference

and i can add scope link to route table 200 via ip command:
sudo ip route add 10.10.56.0/21 dev eno1 scope link table 200
