Details

Example: in Firefox Desktop, the navigator.vibrate() exists, but does nothing. To allow capability detection and enable fallbacks, navigator should not expose a `vibrate` if it will not work.

Normally, I could do the following:

if ('vibrate' in navigator) {
    navigator.vibrate(/*...*/);
} else {
    // fallback action
}

but due to this bug the second branch will not be reached.
Is this a duplicate of bug 838614 ?
