Does microdot WebSocket support Sec-WebSocket-Protocol (sub-protocols) ?

[QGB]

https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_client_applications#creating_a_websocket_object

https://github.com/aaugustin/websockets/blob/main/src/websockets/headers.py#L441

new WebSocket('ws://' + location.host + '/ws',['tty']) cause microdot websocket close. And got 1006 error in javascript.

There is no support for subprotocols at this time.

I don't know what you are you showing me. As I said, the Microdot websocket implementation does not support subprotocols at this time.
