Worker "Quick Edit" websocket disconnected

When using the “Quick Edit” feature for workers, after 20 seconds, the console shows an error message saying the websocket disconnected. If I then click the button saying “Reconnect Dev Tools”, 20 seconds later I get the same error message.

I’m using Firefox 99.0.1. I have tried disabling all of the addons that might block a connection. I wouldn’t be surprised if this is my own fault somehow, but I’m not sure what could be causing the problem.

Has anyone else experienced this? Any idea how I might fix it?
