Control PubSub stops listening/Extension config won't change on frontend

[BarryCarlyon]

Brief description

The following two PubSub topics pertaining to extensions don't like to reconnect

• Twitch Extension pubsub.
• Twitch Extension control pubsub.

The former:

https://dev.twitch.tv/docs/extensions/reference#helper-extensions

The listen events described there

And the latter:

The Extension Control pubsub, the one that live changes what extensions are active on a give stream.

Both of these topics, are not "reconnect" safe on the main Twitch PubSub.

Resulting in the wrong extensions being loaded, or extensions no longer receiving PubSub broadcasted events

How to reproduce

Leave a Twitch stream open for an amount of time.

Today's issue occured on itmeJP's channel after about 30 minutes. The loaded extension stopped receiving PubSub broadcasted events.

Expected behavior

Whenever Twitch "main" pubsub reconnects, or whatever, reconnect the extension control and extension listen topics.

Additional context or questions

It's both an extensions issue and a main website issue.
It's unclear what can cause the main Twitch pubsub feed to die.

Additional Example:

Cohh was live with "CohhVideo" loaded in the video Slot
He goes offline
I switched the live extensions as follows

• No extension loaded
• DF extension loaded
  (Two seperate API requests)

Cohh goes live for DF, CohhVideo showed as in the slot for me, instead of what was selected. As my browser has DC'ed the control topics.

Whatever is happening also seems to effect the title/game auto updates beneath a stream

EXT-1157

Consider this graph

This extension is only active on a Wednesday afternoon.

But due to this bug, a twitch player will not update title, game information automatically (without a reload), AND will not update the active extensions. So a user may have a page open with a stream open, and it stops listening to all real time updates for all data.

This also affects the extension pubsub service inside an extension.

Just another way to display the issue

Or this one

Video extension: the spike is stream up.
I switched off the left extension and turned on the right extension.

But still 600 people loaded the wrong extension at stream up, as 600 people has Disconnected from the control pubsub (for title, game and extension real time updates)

Today

Streamer changed extensions in the video slot using the dashboard. (config b)
I was stuck with the previous configuration (config a)

Reload the page, right config (config b active)

Fast forward 3 1/2 hours or so

I changed the extensions on the same channel to the previous configuration/what was active in the video slot
I was stuck with the (config b) again
Instead of seeing config A again, I'm seeing config b

Reload I get config A as expected

Today this was in Safari.
Laptop did not go to sleep.

Issue is present across browsers
