Looking at some older 2.12 systems, I'm beginning to wonder whether the warning prompt displayed consistently at all, even when editing MARC records. I was just on a 2.12.0 system, which is what was current at the time Andrea and I reported our previous results, and I was unable to trigger the warning prompt while editing MARC records. I was able to trigger it once when using a later 2.12 system, but was unable to replicate it on subsequent attempts. In any case, the patch still isn't causing the prompt to appear.
