So the kernel version is ruled out as culprit.

I used the 11.3.0 netinst image to install, but everything is up to date. I've confirmed the behavior independently on two fresh installs.

I suspect your "very little customization" (since you're doing
networking stuff) or the "VBox Guest Additions" (since they mess with
network interfaces). In order to test this, I used
debian-11.3.0-amd64-netinst.iso from the archive to install a vm, but in
my case QEMU/KVM. German localization and no task selected but
task-ssh-server.

The behavior is good. (disable_ipv6=1 works for me as intended) That
seems to confirm my original hunch.
I'm curious about the outcome, so maybe follow-up to this list please?
Any potential bugs should be reported. But probably I won't be able to
spare time to test VirtualBox.
