proxyHeaders are not set on Web Player

[abusenet]

For the add-on I'm working on, I need to set a Cookie on the request's headers for the stream's URL. I did that through stream.behaviorHints.proxyHeaders.request.Cookie with stream.behaviorHints.notWebReady set to true.

While that works for StremIO apps, it does not seem to send the headers when watching on the Web Player. Please support it.
