Issue with print attached to JS

I am having an odd issue with print messages coming out of JS.
I have lists coming out of JS, but they do not print when fed into the print object, unless I also send it a bang. See attached patch, script and movie that shows this. The movie is made with an older beta, but I also checked on the most recent beta (info appended), and had the same result.
