Python Kernel Websocket: 401 Error when using Safari Browser

[amp-man]

Hi,

When using Apple Safari 12.0.3 as Browser:
In Jupyterlab Lite, running the GETTING STARTED.ipynb unfortunately does not produce any Output.
The small indicator circle next to "Python 3" Kernel name is grey and says in the tooltip "Kernel Reconnecting".

Running a JavaScript Console in Safari gives me the following error:

[Error] WebSocket connection to 'ws://hassio.local:7777/api/kernels/4c7bdd3f-248e-4a44-b2b8-2955a2439ba5/channels?session_id=16242f9a-e2c6-480d-bbd1-287ee128c5fd' failed: Unexpected response code: 401

The same test in Google Chrome works just fine and does not produce any errors in JavaScript Console

I suspect this to be an issue related to this add-on, as Safari is officially supported by JupyterLab.

Steps to reproduce:

1. Use Apple Safari 12.0.3 as Browser
2. Install jupyterlab-lite addon with default config (Port: 7777) on HASS.io 0.88.2.
3. Run "GETTING STARTED.ipynb" Notebook
4. Observe output/JavaScript Console
