Stats continue to update in dashboard after experiment ended

[Chris Lowis]

Hi! 

I clicked the "make this option permanent" button next to an option in the vanity dashboard after I was satisfied that I had enough participants to make the decision. The experiment changed state in the dashboard, but checking it again today I see that the numbers continue to update (the selected option now has more participants). Is that expected behaviour? I expected the experiment results to "freeze" at the point where I stopped the experiment. 

I am using the javascript registration and a redis background, if that is relevant. 

Cheers, 

Chris
