JS Bin example doesn't work with WebSocket in Internet Explorer 11 and Microsoft Edge

[flowersinthesand]

Both browsers have problem in opening a connection through WebSocket. Microsoft Edge throws a vanilla Error instance and Internet Explorer 11 throws an error of SecurityError around the line 39-42.

Other transports are working correctly in both browsers.

Oops, this error only occurs in JSbin but a vanilla WebSocket echo test does work in there. I'm not sure yet.

Renaming uri from "http://localhost:8080/cettia" to "http://127.0.0.1:8080/cettia" works.
