I don't know how to do a "backport" but would be happy to learn :-)

This PR should be able to be applied to the 1.0 release tree without issues as far as I know.

@LarryWoestman we'll do the backport for a 1.0.1 bugfix release

I was able to figure out a test for this issue, so added the test as well with the latest force-push.

@LarryWoestman could you resolve the conflict in this PR?

I would be happy to fix it if I could figure out what the conflict is. Can you be more detailed about what the problem is or what I can do to figure out what the problem is?

Thanks!

I noticed that #18539 was already merged when it was supposed to wait until this issue was merged. That might be the cause of the conflict since the conflict isn't in code that I modified.
This conflict isn't in a file that I modified. The conflict isn't even in the CAM directory tree :-)
I don't see a conflict when I download the latest version of "main" to my "staging" branch.
Perhaps this is caused by the pre-commit-ci bot checkin?
I am currently in the process of building and testing a "staging" branch that is up to date with the main branch except for my changes. I will force push a new version of the "staging" branch as soon as that is done. It might take me until my evening since I have to go out with my wife :-)
Yes, the change is caused by the pre-commit-ci bot's change. I don't know what to do about that.

I have force pushed an up-to-date version of the "staging" branch.

I don't see any pre-commit-ci bot changes to this force push, so perhaps the problem has gone away? :-)
