Patch for 1748884 (once landed) will integrate the initial infrastructure needed to support WebVTT for Picture in Picture. All changes are currently done in PictureInPictureChild.jsm, but WebVTT logic could be encapsulated into its own class `PiPWebVTTHandler` to make the PiP child codebase less bloated. The PiP child can then simply call a function to display WebVTT captions provided by this new class.
