Ok - If we can figure out the patch in 3.17 that fixes it - I can add it to release-3.16

Or we can create a branch release-3.16-moose - and add in whatever patches you want. [and you can use that commit/hash/branch in MOOSE/petsc submodule]

[I'm hesitating to add the attached patch to release-3.16 branch. If this patch is something that we would merge all the way to main - it would could add it in to the release-3.16 branch]
