AdGuard 2.10.8 extension for Edge blocks Spotify web player song play

[veronikasav]

Steps to reproduce

1. Go to https://open.spotify.com/
2. Try to play any album.
3. "Play" button is blocked.
4. The album icon in the left-down corner is missing.

Whitelisting the website doesn't work. If I disabled AdGuard, the album icon is back, songs can be played, no problem at all.

@maximtop the issue is likely to be caused by the WebRTC/WebSocket overriding code.

AdGuard is also blocking the XProtect Web Client (Milestone) video feed via WebSockets on MS Edge. I believe it's the exact same issue. Whitelisting the site doesn't work. Disabling the extension works. The fixing of issue #1014 is probably the culprit.

@viniciusvillas yep, that must be it, thank you for chiming in!

It seems that the only viable way is to simply rollback #1014 :(

Edge behaves unpredictably when we override WebSocket.
