When strategizing about these types of fixes, I think this one is risky because we are changing the behaviour of all of the utilities that use this while only validating this specific utility. I was thinking it would be better to move them over with tests that show the functionality that we are trying to replicate so that going forward we will make sure that we never make changes that mess with that behavior.

Would it be possible to make a new macro for this to keep all of the other utilities keeping the same behaviour so that when we migrate the other utilities we can make sure to have regression checks?

I think it is worth to try changing the macro directly for #9810
