Bugzilla

For certain WebVTT compatible sites like ted.com, their track [modes](https://developer.mozilla.org/en-US/docs/Web/API/TextTrack/mode) do not always update from "hidden" as one expects, particularly when tracks are visible on a video. Bug 1754549 aims to obtain a collection of sites, for which we "ignore hidden mode", via [remote settings](https://firefox-source-docs.mozilla.org/services/settings/#usage). 

However, someone in the PiP team (or any Mozilla staff really) must set up the remote settings themselves and create the override list that we need. Steps to setting this up can be [found here](https://remote-settings.readthedocs.io/en/latest/getting-started.html).

To give us an idea of how our data could look, here is a simplified example:
```
//collection of overrides named as "pip-webvtt-overrides"
const RemoteSettings("pip-webvtt-overrides").get();
/* records ==
 [
   {
     id: "ted",
     url_patterns: ["https://*ted.com/*"],
     should_show_hidden_mode: true,
   },
 ];
*/
