Thanks for the bug report, Mikko.
I confirmed that this bug happens on both Bionic and Focal, but doesn't
happen (or at least doesn't happen in the same way) on Groovy.
Bear in mind that, when running this command using Groovy's rsync, I
see:
$ rsync --delete-missing-args --files-from=list a b
file has vanished: "/tmp/rsync-bug/a/1/2"
WARNING: parent dir is absent in the file list: 1/2
default_perms_for_dir: sys_acl_get_file(1/2, ACL_TYPE_DEFAULT): No such file or
directory, falling back on umask
rsync warning: some files vanished before they could be transferred (code 24)
at main.c(1330) [sender=3.2.3]
This is a different error from the one reported in the bug, and I think
it's worth investigating whether it is another bug, or if it's just an
expected error this time.
FWIW, the patch needed to be backport in order to fix the initial bug on
Bionic/Focal rsync is:

Allow a missing parent dir when --delete-missing-args was specified.

Could you update the rsync package or backport the fix?
