Steps to reproduce the problem:
var s = new webkitSpeechRecognition();

s.onresult = function (event) {
    console.log('user told us to "enter fullscreen"');

    document.body.webkitRequestFullscreen();
};

s.start();

What is the expected behavior?
The code should be able to successfully request fullscreen mode.

What went wrong?
Chrome prevents the code from doing it.

Did this work before? No 

Does this work in other browsers? No
 For now, its not possible to toggle the browsers full screen mode in a self-implemented voice command since chrome reports this error:

> Failed to execute 'requestFullscreen' on 'Element': API can only be initiated by a user gesture.

But actually, telling the browser "go to fullscreen" is kinda user gesture. What do you think about this? Should there a possibility to create new Instance of webkitSpeechRecognition with the right, to call webkitRequestFullscreen somewhen in its context?
