Calling listen inside onAuthorized, listen callback'ed four times

Extensions
3

Did you get a resolution for this or have to hack it? I have encountered the same issue when trying to subscribe viewers to their PubSub whisper channels. With the following code

// Twitch function handlers
var twitch = window.Twitch.ext;
var firstTimeOnly = true;

twitch.onAuthorized((auth) => {
    console.log("Twitch: onAuthorized called");
    console.log("The channel ID is", auth.channelId);
    // console.log("The extension clientId is", auth.clientId);
    console.log("My Twitch opaque user id is", auth.userId);
    // console.log("The JWT token is", auth.token);

    if (firstTimeOnly) {
        firstTimeOnly = false;

        console.log("Subbing to pubsub whisper");
        // Listen to this viewer's private PubSub whisper channel
        twitch.listen('whisper-abc'+auth.userId, (target, type, msg) => {
            console.log("New Twitch PubSub whisper:", msg);
        });
    }

});

My console output is:

Twitch: onAuthorized called
The channel ID is 174234373
My Twitch opaque user id is #############
Subbing to pubsub whisper
*****EBS SENDS 'hello' TO WHISPER******
New Twitch PubSub whisper: hello
New Twitch PubSub whisper: hello

So the callback is subscribed twice. With that boolean lock on it.

The heck?
