systemd rfkill doesn't work

I have the units rfkill-block@bluetooth and rfkill-unblock@wlan enabled.

before rebooting:

ID TYPE      DEVICE                 SOFT      HARD
 0 wlan      ideapad_wlan      blocked unblocked
 1 bluetooth ideapad_bluetooth   unblocked unblocked
 2 bluetooth hci0                unblocked unblocked
 3 wlan      phy0              blocked unblocked

after rebooting:

ID TYPE      DEVICE                 SOFT      HARD
 0 wlan      ideapad_wlan      unblocked unblocked
 1 bluetooth ideapad_bluetooth   blocked unblocked
 2 bluetooth hci0                unblocked unblocked
 3 wlan      phy0              blocked unblocked

expected states:

ID TYPE      DEVICE                 SOFT      HARD
 0 wlan      ideapad_wlan      unblocked unblocked
 1 bluetooth ideapad_bluetooth   blocked unblocked
 2 bluetooth hci0                blocked unblocked
 3 wlan      phy0              unblocked unblocked

I found that the problem is that bt device #2 gets initialized before it gets deactivated:
journalctl -b0 --no-pager --no-hostname | grep rfkill

Any idea on how to make rfkill wait for them?
