[Feature Request] Run dash in jupyter without additional server iframe

[zba]

The problem with Iframe approach is that you need to pass additional ports from your dev environment which could be hard sometime, which makes troubles when you trying to make for example interactive chart, using dash-cytoscape

However as I understand jupyter have own data pipe between server and client.

So may be we can somehow avoid do app.run() the way it creates iframe on 127.0.0.1 ?
