I found the source of this bug.

ember-power-select uses ember-concurrency which uses ember-compatibility-helpers. ember-compatibility-helpers has an included hook that installs its babel transform.

Only the first copy of of ember-power-select that runs calls this._super.included.apply(this, arguments);. This means all the other copies will depend on a broken ember-concurrency.

Sometimes this bug hides because of the way the multiple copies of ember-concurrency get combined into one. Sometimes it probably hides because of ember-cli tree caching that causes only the first one built to actually run. But depending on how your dependency graph falls out, you can end up with the broken copy in your app.

@lifeart - The latest ember-power-select-infinity declares ember-power-select@^2.0.1. The fix for this issue is 2.3.5, which is in range of that. You should be able to upgrade to get it to work.
