feat(patch): show subtites/captions in PiP mode & tablet miniplayer

[castdrian]

Application

YouTube

Issue

YouTube subtitles aren't displayed in PiP mode/tablet miniplayer because they're some screen overlay that just gets disabled

Patch

Ideally the captions would be visible in PiP mode and tablet miniplayer

Motivation

It seems reasonable that captions shouldn't disappear, whilst you're watching something
