Thanks for the bug report. Unfortunately i haven't been able to reproduce this myself. But it has been reported before...
It is something with access to local storage on chrome. I had no problem on other browsers.
Chrome error message:
Uncaught DOMException: Failed to read the 'localStorage' property from 'Window': Access is denied for this document.
