First stab at working code.

Another go, not beautiful, but handles all the edge cases I can throw at it:

• normal blur without submit (run email validation)
• click submit (run full form validation)
• press down on submit button, but drag off (run email validation only, no submit)
• press down on submit button, but drag off outwith browser chrome (run email validation only, no submit)

Well the tests pass and the behavior is what I expect in Chrome latest.

+1 From me, will want to sit on this a day to think about it cause I really hate this stinking bug.

This would finally close #19

Thanks for getting to this. It's less janky than every other option we looked at, and you even added to the demo.html file!
