I did reproduced the issue.

By changing the end of check() function in
/usr/lib/dracut/modules.d/90lvm/module-setup.sh by this:

[[ $hostonly ]] || [[ $mount_needs ]] &amp;&amp; {
    for_each_host_dev_and_slaves_all check_lvm || return 1
}

I got:
# cat ./etc/cmdline.d/90lvm.conf
 rd.lvm.lv=sagittarius/swap 
 rd.lvm.lv=sagittarius/root

Iirc I replaced for_each_host_dev_and_slaves by
for_each_host_dev_and_slaves_all.

Honestly I don't understand what it change...

Hope this help.
