<pre>Here's the key trick:
function listenerRecieversWithPrototype(proto, emitter) {
let results = new Set;
for (let eventType in emitter._listeners) {
let recordsForEvent = emitter._listeners[eventType];
for (let listener of recordsForEvent) {
if (listener.thisObject instanceof proto)
results.add(listener.thisObject);
}
}
return results;
}
We can check that the number of instances stays the same across reloads or navigations between simple pages.</pre>
