AppArmor profile is not loaded

[erikschul]

Description

When explicitly applying an AppArmor profile, processes run as unconfined.

Reproduce

cat > /etc/apparmor.d/containers/docker-empty <<EOF
#include <tunables/global>

profile docker-empty flags=(attach_disconnected,mediate_deleted) {
  #include <abstractions/base>
  file,
  deny /etc/** wl,

  capability chown,
  capability dac_override,
  capability setuid,
  capability setgid,
  capability net_bind_service,
}
EOF

apparmor_parser -r -W /etc/apparmor.d/containers/docker-empty

docker run --security-opt "apparmor=docker-empty" --rm -it debian:12 bash -c "sleep infinity"

# returns "unconfined"
cat /proc/$(pgrep sleep)/attr/current 

Expected behavior

Processes should run with the AppArmor profile docker-empty.
This works correctly with podman.
