Strange gateway address when using route-table and dispatcher script

[Alexander Rumyantsev]

When not using route-table I'm getting this values in dispatcher script:

DHCP4_ROUTERS="10.1.1.254"
IP4_ADDRESS_0="10.1.1.14/24 10.1.1.254"
IP4_GATEWAY="10.1.1.254"

But when i switch to separate table via route-table setting, I'm getting:

DHCP4_ROUTERS="10.1.1.254"
IP4_ADDRESS_0="10.1.1.14/24 0.0.0.0"
IP4_GATEWAY="0.0.0.0"

Is it a bug or feature?
NetworkManager 1.42.4

Best regards,
