Screenshot of the IPv6 tab

Plasma NetworkManager doesn't apply IPv6 configuration to imported OpenVPN configuration.
Upon importing a VPN configuration with its configuration file, and going on the VPN connection menu to configure it, setting IPv6 method to "Disabled" on the IPv6 tab doesn't  disable IPv6 on connecting to the VPN, as the address is still active and can still issue IPv6 connections.

The "master" NetworkManager connection has both IPv4 and IPv6 connection methods set to "Automatic".

STEPS TO REPRODUCE
1. Import OpenVPN configuration file
2. Disable IPv6 by setting the IPv6 connection method to "Disabled"
3. Connect to the VPN

OBSERVED RESULT

IPv6 address is still active and can make connections (with curl -6 https://example.com for example).

EXPECTED RESULT

IPv6 is disabled for the lifetime of the VPN connection, being re-enabled when the VPN is disconnected.

I opened the VPN settings in Plasma and set IPv6 to "Disabled". Then i opened nm-connection-editor, and there the setting is shown as "Disabled" too. This makes me think that the setting is actually correctly passed to NetworkManager, but either broken on a lower level or it doesn't do what you expect it to do.

When you change the setting in nm-connection-editor, does it have the desired effect?
