Websockets + WebGL throwing exception, Unity 5.4 doesn't allow AddComponent(MonoBehaviour)!

EDIT: It looks like Unity 5.4 simply doesn't allow attached MonoBehaviour with AddComponent(). Any help would be appreciated, I literally can't connect until this is resolved 
When connecting to PUN in Unity 5.4, it's throwing two (related) exceptions:
1) "AddComponent with MonoBehavior is not allowed." It references line 79 of SocketWebTcp.cs which does precisely what it says is not allowed (it's trying to add monobehaviour with addcomponent).
2) This then causes a null reference, not shocking where it didn't allow mb to be added, at line 84 of SocketWebTcp.cs where it attempts to do this: this.sock = new WebSocket(new Uri(ServerAddress));

Hi skeptika,
within your project, create an empty class which is derived from MonoBehaviour. This class can be created as a new script or within the SocketWebTcp.cs file. In the second case open SocketWebTcp.cs and navigate to the end of the file and add the following line of code inside the namespace braces:internal class MonoBehaviourExt : MonoBehaviour { }
Note: MonoBehaviourExt can be a name of your choice.
Now navigate to the AddComponent call (line 79 in unmodified file) and replace MonoBehaviour with MonoBehaviourExt or the name you have chosen for the class.6 -
Thanks for the feedback (good to know it works for you, too) and thanks for the heads up.
We checked 5.4 a while ago but I guess Unity wasn't finished with it. We've been compatible early on but as we broke now, we'll check again.5

It does look like Unity just changed it: http://forum.unity3d.com/threads/please-clarify-using-gameobject-addcomponent-is-no-longer-allowed-and-will-throw-an-exception.412199/
Sorry to be an explicit newb, but since the advice is to "Derive a class from MonoBehaviour and add it instead," how would I do this in the context of SocketWebTcp.cs?0 -

Ty this worked beautifully, feel like a newb for not actually knowing how to do this, but appreciate the assist!
Heads up for the Photon guys, 5.4 brought (which is already out in RC) a few breaking changes that'll have to be changed in Photon to avoid seeing a ton of forum messages like this!
In addition to breaking .AddComponent(MonoBehaviour), they also broke several of the OnSomethingHappened references, removing the On in most cases. Cheers and thanks! 0 -

Yah that's what caught me by surprise, I'd been using 5.4 for awhile in betas with no problems, then suddenly boom it didn't work. All good and thanks!0
