Can javascript actions be made to change the document's activeElement as would happen with real user interactions?

I'm playing with the writing of an implementation of the JSONWire Protocol. The implementation simulates user behaviour (click, navigate, etc.)... my goal is to make a lighter (albeit less feature complete) version of th selenium server.

Now I've noticed that when simulating events (for instance, a click), the document.activeElement property does not change.

I've made this JSfiddle to demonstrate: http://jsfiddle.net/75bq50wa/6/.

You should notice that if you click the "Click me" checkbox, the activeElement changes, whereas it does NOT change when clicking using Javascript.

My interpretation is that only native events alter the state of the activeElement property.

Is this correct, or is there a way to better emulate user events in Javascript?

The W3C Recommendation (http://www.w3.org/TR/html5/editing.html) says:

document . activeElement

    Returns the currently focused element.

This means, you need to additionally focus() the element, in order to correctly simulate a User's click.

See this updated JSFiddle: http://jsfiddle.net/e3vg5k75/
