title: Why I am getting dates also while using Month only picker [PrimeNG]
body: <p>I read the PrimeNG documentation. I opened this issue on github also (<a href="https://github.com/primefaces/primeng/issues/8309" rel="nofollow noreferrer">here</a>). But didn't receive any answer yet. I'm using <code>primeng</code> component i.e. <code>&lt;p-calendar&gt;</code> along with some other primeng components. Here is my code:</p>
  
  <pre><code>&lt;p-overlayPanel #op&gt;
      &lt;div id="comp-render" name="fieldName" ngDefaultControl&gt;
          &lt;div class="all-container"&gt;
              &lt;p&gt;Time selection&lt;/p&gt;&lt;br&gt;
              &lt;div class="ui-g-12 ui-md-4"&gt;
                  &lt;p-calendar view="month" dateFormat="mm/yy" [yearNavigator]="true" yearRange="2018:2022" [readonlyInput]="true" placeholder="Year-to-date"&gt;&lt;/p-calendar&gt;
              &lt;/div&gt;
              &lt;br&gt;
              &lt;div class="custom-control custom-switch"&gt;
              &lt;input type="checkbox" class="custom-control-input" id="customSwitches"&gt;
              &lt;label class="custom-control-label" for="customSwitches"&gt;Comparing&lt;/label&gt;
              &lt;/div&gt;
              &lt;br&gt;
              &lt;p-dropdown [options]="cities1" [(ngModel)]="selectedCity1" &gt;&lt;/p-dropdown&gt;
              &lt;br&gt;&lt;br&gt;
              &lt;div&gt;
                  &lt;p-calendar view="month" dateFormat="mm/yy" [yearNavigator]="true" yearRange="2018:2022" [readonlyInput]="true" placeholder="Previous Year-to-date"&gt;&lt;/p-calendar&gt;
              &lt;/div&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/p-overlayPanel&gt;
  </code></pre>
  
  <p>But Why I'm getting this:

  <p>It should look like this:</p>

  <p>PS: Assume that no bootstrap is being applied.</p>
  
  <p>I tried updating the <code>primeng</code> and <code>primeicons</code> version. Things worked but there are some style issues.</p>
