title: ion-select default value not working with ngfor in ion-select-option
body: <p>This is my ionic code which I wrote for <code>ion-select</code></p>
  <pre><code>&lt;ion-item lines=&quot;none&quot; type=&quot;input&quot;&gt;
    &lt;ion-label position=&quot;stacked&quot; color=&quot;primary&quot;&gt;Skill level&lt;/ion-label&gt;
    &lt;ion-select
      [formControl]=&quot;selectedSkill&quot;
      color=&quot;white&quot;
      class=&quot;ion-padding-start&quot; value=&quot;{{ student.level }}&quot;&gt;
      &lt;ion-select-option *ngFor=&quot;let level of levels&quot; value=&quot;{{ level }}&quot; color=&quot;primary&quot;&gt;
        {{ level }}
      &lt;/ion-select-option&gt;
    &lt;/ion-select&gt;
  &lt;/ion-item&gt;
  </code></pre>
  <p>The default value is working fine when I click the select element once. But it is not prefilled once I open the page.</p>
