ember render hbs swallowing thrown error

I have a simple component integration test:

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

Source code of component.js is like:

export default Ember.Component.extend({
    layout,
    init() {
        this._super(...arguments);
        throw 'my-custom-input component error';
    }
}

While my ember-cli version was 2.3.0, the test was passing. However, after I've updated my ember-cli version to 2.11.1, the test did not pass. The error was:

    actual: >
        false
    expected: >
        true

Why does ember render start to swallow the thrown exception?
