Is your enhancement request related to a problem? Please describe.

No

Describe the solution you'd like

Add a button to share a clean URL of the video.

Describe alternatives you've considered

Erasing extra query parameters manually, which is prone to errors.

Additional context

Sometimes you open the video from a playlist, it carries in the URL a lot of useless parameters, most of the time you just want to share the video itself, not the playlist, not the timestamp, not the index.

The problem here is that big URLs make most people suspicious about clicking on it, so I usually erase extra parameters manually.

Example of bad URL to share:
https://[INSTANCE]/watch?v=TedJQUGLsy4&list=PLR_kEIuPWsgtFJYXBEwzpmTM88rxAYje-&index=0

Good URL:
https://[INSTANCE]/watch?v=TedJQUGLsy4

Technically the share button in video.js give you a clean URL. But it's broken: #3933
