Steps to reproduce the issue

Without trying to invoke the JS gods on this...

while useful in development (in uncompressed js files) the console.warn messages are also showing up on live sites... do we really want to be doing that? its bad practice to output to the console log in production right?

These messages are actually only trigged just before a page "unloads" when a user clicks a button so are rarely seen anyway, unless the log is preserved between navigations

Expected result

Silence. Nothing logged on a live site using the compressed js files.

Actual result

System information (as much as possible)
