Proxy over adb waits for a message indefinitely

[Wyn-Price]

When starting in proxy-over-adb, a request to ws://localhost:8000/?action=proxy-adb&remote=tcp%3A8886&udid=XXX is sent, the server responds with a 101 and the websocket is established.

No more communication happens on the websocket, and the frontend is blank. From what I can tell from digging through the client code, it's waiting for an initial message, but I can't figure out why the server isn't sending anything.

Things like shell, devtools and list_files work, with shell sending an opening message to trigger the server to respond.
