I was coding along and after an hour or so, parts of the IDE (search, scm, open file) didn't work anymore.

Turned out the connection to the code server dropped and reconnection didn't work.
logs from the console:

A workaround is to reload or open another page.

I was able to reproduce it, by capturing WebSocket object to the extension host process from the heap snapshot and closing it. Handshake on the reconnection is broken. Looking into the fix. That’s really hard to reproduce otherwise, because if the connection is completely offline, VS Code treats it differently.
