This was also a clever little trick, which is likewise good to know as a possible solution. In the end, however, I ended up, basically by accident, using it twice anyway, for an actual reason, so the issue went away, but it's good to be aware of these little intricacies, which actually led me to not use this feature in the past since the warnings were a mystery to me and I just moved on, so now that's all resolved and working fine. It's odd what missing one key bit of information that isn't very intuitive or obvious can do in terms of hindering progress and development.
