I opened
<https://salsa.debian.org/kernel-team/initramfs-tools/-/merge_requests/158>
in an attempt to fix this.

If you're able to test the packages from
<https://salsa.debian.org/kernel-team/initramfs-tools/-/jobs/7184963/artifacts/browse/debian/output/>
can you verify that they fix the problem for you?

Ben.
