The client is Mullvad VPN, but without looking into it further, I'm not
confident if it is them or Apple that should take the blame here.

Their website is:
    https://mullvad.net/

Note that while the VPN itself is a paid service, the license of their
VPN client is GPLv3:
    https://github.com/mullvad/mullvadvpn-app/

If someone is able to trace this back to something that they did wrong,
I'd recommend sending them a bug report.  They are typically quite
responsive to issues.  I don't understand this issue well enough to do
that myself, and I unfortunately don't have the time to invest into it.

Thank you for the quick fix, Robert!
