title: ngx-chips tag-input-dropdown does not show autosuggest in iPhone
body: <p>I have implemented ngx-chips for an email CC field. It works perfectly in my Android phone using Chrome. But, in iPhone, the autosuggestion does not show up.</p>
  <pre><code>&lt;div class=&quot;required form-group col-md-12 col-sm-12 col-xs-12&quot; &gt;
      &lt;label class=&quot;control-label&quot; for=&quot;email.emailCc&quot;&gt;CC:&lt;/label&gt;
         &lt;tag-input [(ngModel)]=&quot;emailList&quot;  [onlyFromAutocomplete]=&quot;true&quot; theme='bootstrap'&gt;
          &lt;tag-input-dropdown [autocompleteObservable]=&quot;items&quot; [showDropdownIfEmpty]=&quot;true&quot; [dynamicUpdate]=&quot;false&quot;&gt;
          &lt;/tag-input-dropdown&gt;
         &lt;/tag-input&gt;
   &lt;/div&gt;
  </code></pre>
