Ember.run.later is halting under certain circumstances

[rondale-sc]

Here is a twiddle demoing it for 1.13.6. I've also tested this for 2.0.0:

The gist can be found here:

The demonstration has a timer value being updated via Ember.run.next continuously. When it is running calls to Ember.run.later will halt the update of the value until the full duration of Ember.run.later has expired.

If Ember.run.later is replaced with a simple setTimeout there is no halting. I did not experience this problem on 1.12.x.

If I can assist in any way please let me know. ❤️

At a glance, this sounds like a duplicate of #10479 which in turn is an upstream bug at BackburnerJS/backburner.js#135.

@dtetto - Yes, I just came to the same conclusion. Thank you for linking!

Consolidated some of the related PR's together: BackburnerJS/backburner.js#146

Will be fixed by #12331, but @stefanpenner will have to review to see if this is eligible for backporting.

I'll take care of the backport

Shameless Bump. This was the root cause of an issue a customer reported for us.

We're still on 1.13.x and would really love to get this fixed.

I haven't had time, @workmanw care to submit a PR backporting backburner?

[workmanw]

@stefanpenner If you give me a little bit of direction, I'd be more than happy to. It seems to be fixed in backburner and backburner seems to be pulled in via bower (https://github.com/emberjs/ember.js/blob/release-1-13/bower.json#L9). So is the PR just as simple as updating the 'bower.json' or is there more to it?
