I started testing binaries from the release history page: https://launchpad.net/ubuntu/+source/grub2-signed/+publishinghistory
The last working one is: https://launchpad.net/ubuntu/+source/grub2-signed/1.116 https://launchpad.net/ubuntu/+source/grub2-signed/1.116/+build/17166212/+files/grub-efi-amd64-signed_1.116+2.02+dfsg1-12ubuntu3_amd64.deb
The first broken one is: https://launchpad.net/ubuntu/+source/grub2-signed/1.117 https://launchpad.net/ubuntu/+source/grub2-signed/1.117/+build/17277557/+files/grub-efi-amd64-signed_1.117+2.04-1ubuntu1_amd64.deb
So indeed 2.02 works and 2.04 doesn't. I will check if the problem affects other distributions as well.
