It’s a Safari issue. Editing modules would appear to work as expected on Firefox on Mac OS X.

Let me know (a) if you want to troubleshoot this further and if so (b) if there’s any debug information I can send your way to help with this or where I should look for clues to what’s causing this.

Having to use another browser is a pain, but not a dealbreaker as I expect most of the clients are using something on Windows anyway.
