Asserting error thrown no longer works as of 2.11

The following test, no longer run after we start to use 2.11.1.

test('it throws error my-custom-input is called', function(assert) {
    assert.throws(() => {
        this.render(hbs`{{my-custom-input}}`);
    }, /my-custom-input component error/, 'Error must have been thrown');
});

I saw mocha users had faced with nearly the same problems: https://github.com/emberjs/ember-mocha/issues/141

This was fixed by https://github.com/emberjs/ember.js/pull/15871, which essentially reverts https://github.com/emberjs/ember.js/pull/14898 and adds a bunch of tests.

Just came across this same issue while attempting to update an addon from ember/cli 2.9. Has anyone found a decent workaround for ember-cli-chai usage?
