Thanks for reporting this, AnrDaemon! I'm not shure where exactly the issue is, probably grub script should be modified in a way that if it detects that the ESP on the raid it looks into /proc/mdstat and iterates the process with all the component devices. Or it should pass some extra args to efibootmgr, as reported :)
