It doesn't seem relevant to the bug you posted, but as long as you're here... I'm always annoyed by the vagueness of JSON.parse syntax errors. Instead of showing the source file and line number of the call to json.parse (or even better the location of the syntax error in the json string it failed to parse) I get "uncaught syntax error in index.html:1". I know now that that usually means i've forgotten to wrap a json.parse in a try..catch, but it's caught me out a few times.
