At first I thought it was related to https://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git/commit/?id=1e19b01be31fc5264a84d246023ecf29e44949df&context=25&ignorews=0&dt=0, and later I thought it was related to https://bugs.launchpad.net/bugs/1762748. However, I added the bionic archives to my Xenial instance and updated e2fsprogs and cloud-utils, then tried to grow the disk past 2048, and ran into the reboot issue again.
I agree it was very close to, and the recreate information in that bug helped me narrow down what I was seeing.
