title: actionMenuTextColor not working when using ?/attr
body: <p>I am trying to change the color of the text menu item in my toolbar</p>
  <p>When using :</p>
  <pre><code>&lt;style name=&quot;Base.App&quot; parent=&quot;Theme.MaterialComponents.Light.NoActionBar&quot;&gt;
          &lt;item name=&quot;actionMenuTextColor&quot;&gt;@color/blue&lt;/item&gt;
  </code></pre>
  <p>It works but when using :</p>
  <pre><code>&lt;style name=&quot;Base.App&quot; parent=&quot;Theme.MaterialComponents.Light.NoActionBar&quot;&gt;
              &lt;item name=&quot;actionMenuTextColor&quot;&gt;?attr/colorPrimary&lt;/item&gt;
  </code></pre>
  <p>It doesn't.</p>
  <p>Any idea?</p>
  <p>Edit 1 :</p>
  <p>toolbar styling is the following</p>
  <pre><code>&lt;item name=&quot;toolbarStyle&quot;&gt;@style/Widget.App.Toolbar&lt;/item&gt;
  
  &lt;style name=&quot;Widget.App.Toolbar&quot; parent=&quot;Widget.MaterialComponents.Toolbar.Primary&quot;&gt;
          &lt;item name=&quot;materialThemeOverlay&quot;&gt;@style/ThemeOverlay.App.Toolbar&lt;/item&gt;
          &lt;item name=&quot;titleTextAppearance&quot;&gt;@style/Widget.App.Toolbar.TitleTextAppearance&lt;/item&gt;
      &lt;/style&gt;
  
      &lt;style name=&quot;Widget.App.Toolbar.TitleTextAppearance&quot; parent=&quot;TextAppearance.App.Headline6&quot;&gt;
          &lt;item name=&quot;android:textStyle&quot;&gt;bold&lt;/item&gt;
      &lt;/style&gt;
  </code></pre>
  <p>Edit 2 :</p>
  <p>using</p>
  <pre><code>&lt;style name=&quot;Base.App&quot; parent=&quot;Theme.MaterialComponents.Light.NoActionBar&quot;&gt;
              &lt;item name=&quot;actionMenuTextColor&quot;&gt;?attr/colorPrimaryVariant&lt;/item&gt;
  </code></pre>
  <p>actually works. But again, not <code>colorPrimary</code></p>
