Unhandled error event: Error: read ETIMEDOUT cause request stuck

I am also running into this issue where a failure to connect just hangs requests. This has happened with all of the combinations of connection patterns I can think of:
Connect right away.
Use lazyConnect=true and call connect()
Use lazyConnect=true and call a command like set.
I replicate this issue by simply not having redis running and the debug logs DEBUG=ioredis* produce:
> conn = new Redis({ port: 6379, host: 'localhost', lazyConnect:true });
> conn.connect().then(console.log).catch(console.error)
  ioredis:redis status[localhost:6379]: wait -> connecting +2m
  ioredis:redis status[127.0.0.1:6379]: connecting -> connect +2ms
  ioredis:redis write command[127.0.0.1:6379]: 0 -> info([]) +1ms
# Wait a long time
> conn.status
'connect'
I would definitely like to see the connection error propagate out to the caller, otherwise I am having to build my own connect timeout behaviour.
          
One poor workaround is to set enableOfflineQueue: false on the instance. In this case if you send any command while the connection isn't working they will immediately error:
Error: Stream isn't writeable and enableOfflineQueue options is false
    at Redis.sendCommand (/Users/stephenlewchuk/span/cloud/packages/app-api/node_modules/ioredis/built/redis/index.js:634:24)
    at Redis.set (/Users/stephenlewchuk/span/cloud/packages/app-api/node_modules/ioredis/built/commander.js:111:25)
    at repl:1:6
This does prevent the usage of lazy connect requiring you to manage connection on your own.
