Not a huge deal (i've already approved) but if this is functionality we don't want to regress, then it would be nice to get a test to verify it.

I don't really know if the contents of a debug message is part of what we should be testing 🤔 Like, I don't know if this is really something developers should depend on so much as it is just useful information to figure out where something went wrong. Yay or nay?
