From Christian:
everytime the pod terminal updates we send this:

const data = Base64.encode(JSON.stringify({ Height: rows, Width: cols }));
this.ws && this.ws.send(`4${data}`);
but widget that is used for WebTerminal does not seem to send it.

It's critical for WebTerminal since even kubectl edit command does not work with the default terminal size.
