Brief description

If a streamer changes the active game on a channel.

onContext in "non popout mode"

Will get one time window where the game updates to the new name correctly.
But then resets to the previous game for a few minutes. (around 3)
Before updating again to the correct game.

I'm seeing a similar issue with a stream changing the category mid-stream. The first load of the page after changing the category will provide the previous category in the onContext callback. The game category does not update after any amount of time. The second load of the page will show the correct category in the onContext callback.

Likewise, when starting a stream, the first viewer will see an empty string for the 'game' property in the onContext callback. After ~30 seconds, the correct game category is populated in the callback.
