Some ppl don't like that the placeholder has an American style indicator for closed captioning and/or subtitles (note, the older player had the SAME indicator)

videoJS itself actually has two different subtitle buttons depending on the language used. We currently always use CC (mostly because it was easy implement with text)

If we want to use the other icon, we:

1. need that other style icon (not sure if we can extract and reuse it, it might muddy licensing of the various components). Possibly see T302150: Add 'Subtitle', 'Picture-in-Picture' and 'Restart' icons in Design Style Guide, Codex & OOUI
2. add it to the placeholder style sheet
3. Decide if we too want to flip usage depending on language
