Describe the bug

Switching transcript language only changes transcript; switching captions also switches the transcript. This means that although you can use the transcript in a different language from the captions, you need to do it in a specific sequence for it to work.

I think it may make sense that if you switch captions language while the transcript is hidden, it can be assumed that you want everything in the same language. But if you switch it while the transcript is visible, you're controlling them independently.

This is a tricky question, because it depends a lot on user flow. Users should be able to have these views in different languages; but it adds extra steps if they don't switch together. In my opinion, however, if you're in the 'Captions' controller, you should only expect it to change captions, and if you're in the transcript language controller, you should only expect it to change the transcript.
