Richard Macklin 39493185d3 Remove explicit document receiver from add/removeEventListener calls ... This allows ActionCable to be used in a web worker, where the `document` global is undefined. Previously, attempting to use ActionCable inside a web worker would result in this exception after you try to open a connection: ``` ReferenceError: document is not defined ``` The visibilitychange event won't ever get triggered in a worker, so adding the listener is effectively a no-op there. But the listener is mainly a convenience, rather than a critical piece of the javascript interface, so using ActionCable in a worker will still work. (And you could listen for visibilitychange yourself in a window script, then tell the worker to reconnect if you still want that behavior.)		2019-01-15 22:14:33 -08:00
