the method above doesn't fully work, since even though grub doesn't pass the
subvol= option to the kernel, it still tries to find kernel at full path,
including the subvolume name.
e.g. in /boot/grub/grub.cfg there are lines like:
linux /@/boot/vmlinuz-5.13.0-20-generic

I've experienced this as well, thanks to @jseiters I was able to perform
a rollback. But is definitely not a nice experience when urgently
needing the rollback for the first time!
Hope It's fixed.

from the line GRUB_CMDLINE_LINUX="rootflags=subvol=${rootsubvol}
${GRUB_CMDLINE_LINUX}" in the file /etc/grub.d/10_linux I can boot from the rw
snapshot snapper makes when I issue the command:
sudo
Interesting... I still can't easily test right now, but if you try to
mount the device manually, possibly from an live disk (`mount /dev/sdXX
/path`), does the right subvol get mounted?

1- remove subvol=@
2- also add the same root ID with
UUID=ce4d5d13-5ec7-4b2f-b519-569e04729d1e /.snapshots btrfs
subvol=@/.snapshots 0 1
as OpenSuSE fstab.

So I think I know why this doesn't work under Ubuntu and it's related to
the mount options Ubuntu sets by default for btrfs for a new
installation.
By default, Ubuntu installs systems with btrfs into a subvolume called @
and the home directory into a subvolume called @home. It then proceeds
