some terminals and type in them the window or restart VS Code they don't persist Started happening in OSS on Wednesday July 5th
is undefined !
it gets set to !
that's the return value (see )
yes, true. but the call returns so it's getting reset somewhere. not via !
I'm on to the cause... The process is getting killed after detaching on reload, so reconnect breaks: Revive after restart is working for me.
Ah found it: Investigating...
Parsed state is null so reconnect stops here:
