extra } crashes update-grub in eaon w/zfs

Despite the attempted patch to prevent a double } } by 10_linux_zfs in grub.cfg for pure zfs systems, the failure remains in the latest eoan.
Total install failure results crashing do-release-upgrade. Critical.
A debug run follows, then the generated file with the extra }

I added a set -x at the top of the loop. the results were
