strange ember behaviour

components.my-leaky-component.js

import Ember from 'ember';

export default Ember.Component.extend({
  willDestroyElement() {
    this.$().remove();
  }
});

controllers.application.js

import Ember from 'ember';

export default Ember.Controller.extend({
  appName: 'Ember Twiddle',
  someCondition: true,
  actions: {
    makeMeDisappear() {
      this.set('someCondition', false);
    }
  }
});

templates.application.hbs

{{#if someCondition}}
	<p>Hello</p>
	{{#my-leaky-component click=(action "makeMeDisappear")}}
		<button>Click me</button>
	{{/my-leaky-component}}
{{/if}}

<p>This is not inside the if block but will still disappear</p>

{{outlet}}
