When user logs out Meteor.user() becomes undefined while Meteor.userId() is still a string

[ksinas]

During logout sometimes user becomes undefined while userId holds the previous value
Occurs on versions 2.1.1 and 1.11.1 on Chrome browser

Reproduction

Register autorun on the client

Tracker.autorun(() => {
  console.log(Meteor.user(), Meteor.userId());
});

Open the console and do the following several times

// 1
Meteor.loginWithPassword({ username: 'user'}, 'password')
// 2
Meteor.logout()

Expected behaviour

// console output
someUserId, { _id: 'someUserId... }
null, null

Actual behaviour

// console output
someUserId, { _id: 'someUserId... }
someUserId, undefined
null, null

My guess would be that Meteor.defer() is not working correctly on chrome browser. I had issues related to that here

AFAIK the logging out process is async operation. You can call Meteor.loggingOut() function to get a current state.

So, if you'll log it, it should be like:

// console output
someUserId, { _id: 'someUserId... }
someUserId, undefined, true <--- Meteor.loggingOut()
null, null, false

My point is that behaviour was inconsistent between browsers. However, I can't reproduce the issue on chrome 90. I guess the issue can be closed
