Not sure if this i in anyway related but the symptoms is very close to what you saw with MaaS and Grub 2.02.
Issue that I have seen will occure on 2.06 and 2.16 as well. My environment is not MaaS but I am using grum from Ubuntu and since the symptom is very close I thought I would share it my bug report here in case it can help in any way. I got a method to reproduce the issue that is as efficient as it gets. For me, I only see issue on certain hardware, and I like to think it could be an issue with device firware, but I do not know how to prove my theory.
