Ydoc keeps trying to reconnect to Language Server after close

[hubertp]

After closing a project in a local dashboard, Ydoc keeps trying to reconnect (and fail):

app/ydoc-server-nodejs dev:watch: Language Server transport error: ErrorEvent {
app/ydoc-server-nodejs dev:watch:   type: 'error',
app/ydoc-server-nodejs dev:watch:   defaultPrevented: false,
app/ydoc-server-nodejs dev:watch:   cancelable: false,
app/ydoc-server-nodejs dev:watch:   timeStamp: 35370090.512761
app/ydoc-server-nodejs dev:watch: }

Messages do not stop, process consumes 100% of CPU.
To see the logs for Ydoc run with YDOC_LS_DEBUG=true.
