Previously, if a user temporarily disconnected while there was a pending call, we would fail to cancel such pending call when the caller left the room. This was due to the caller reconnecting and having a different connection id than the one originally used to initiate the call.
Zed Server
This crate is what we run at https://collab.zed.dev.
It contains our back-end logic for collaboration, to which we connect from the Zed client via a websocket after authenticating via https://zed.dev, which is a separate repo running on Vercel.
