Description Jason Williams 2018-07-12 10:10:09 PDT 
Steps to reproduce the problem:
1. Navigate to https://codepen.io/jasonwilliams1/pen/XBbZjL
2. Focus on the textbox
3. Press shift-tab to move focus into the radio button group
4. Press spacebar to check the radio button
5. Press spacebar to redundantly check the radio button
6. observe no additional click event in the console

What is the expected behavior?
Right now its not clear, I don't see this mentioned in the specification either. 

What went wrong?
I should be expecting additional click events in the console, but only 1 fires

Firefox, Edge and Internet Explorer fire multiple events for each time i press spacebar
