Add support for the watch operator to be called from Web Workers.
Use case, using the library observable-webworker the message reception is being done throw an Observable input$, in this sense inside the Worker we can have the watch operator to see the marvels from the Worker tasks, and debug them easily.

But when I try to use it, the library is using HTMLElements, HTML Events, etc, for which the Worker as no access to it, and then it fails. Maybe we can have a watchWorker alternative to run in a separate worker and communicate with the plugging using messages?

Watch operator uses window.postMessage function which worker has no access to. I think that this is not possible without changes on observable-webworker.
