Why isn't localStorage persisting in Chrome?
Ok. Thanks must go to pimvdb on this one but here's the solution.
<!DOCTYPE html><html><head><script type="text/javascript">function saveStuff() { sessionStorage.setItem('sessionKey', 'sessionValue'); localStorage.setItem('localKey', 'localValue');}localStorage.getItem('localKey');sessionStorage.getItem('sessionKey');</script></head><body><button type="button" onclick="saveStuff()">Save</button></body></html>Summary seems to be that that you must attempt a read of the key in order to persist it.
Conclusion: WTF.

I couldn't figure out why I couldn't see something in my localStorage in Dev Tools, but could see it in the console when typing localStorage. Well, if you store something with Dev Tools open, you won't see Application -> Local Storage have anything listed for your host. When I closed/reopened Dev Tools, I could see my data.
So, in conclusion, close/reopen Dev Tools.
