Bug 113748 – EventSource 'close' event doesn't fire when computer put in sleep mode

• Status: UNCONFIRMED
• Component: WebCore Misc.

var source = new EventSource(url);

source.onopen = function() {
	console.log('opened');
};

source.onclose = function() {
	console.log('closed');
};

Reproduction steps:
1. Run the above code, where url points to a web page that supports SSE
2. Put your computer in sleep mode
3. Take your computer out of sleep mode
4. console.log(source.readyState == EventSource.CLOSED); // will print true

The 'close' event should be fired because the connection was cancelled and the object's readyState was set to EventSource.CLOSED.
