Then set a background color?
you need to handle this for if a user changes from light to dark more, if you are not setting a background color on your extension itself you are at the mercy of any changes Twitch does or does not do, so the correct thing to do is to set a background color on your extension. And add a color change for dark/light mode, if you want to offer two different themes
Because thats what it looks like, to the left would be the stream you are watching/have open
