Was thinking maybe we should switch this to `js-current-email` to fit the way we started naming classes for objects that are accessed via javascript. But it may not be worth changing because everything else here really uses this sort of naming convention and sparkart-js is going to be replaced by the customer portal for a lot of logic.

I guess we should leave this for now and if we're still using this sort of stuff in the future post customer portal we can do a style pass on it to update to the newer format we've been using. Not critical for now.
