CKEditor placeholder icon not showing in toolbar
<p>The placeholder icon is supposed to automatically display in the toolbar but it doesn't.  Everything else is working just fine.  It's a very simple implementation.  Why is it missing??</p>

<p>JAVASCRIPT CONFIG FILE</p>

<pre><code>CKEDITOR.editorConfig = function (config) {
    config.height = 500;
    config.toolbar = 'MyToolbar';
    config.extraPlugins = "placeholder";
    config.extraPlugins = "widget";
};
</code></pre>

<p>HTML</p>

<pre><code>&lt;textarea id="editor1" cols="80" name="editor1" rows="10"&gt;Hello world&lt;/textarea&gt;
&lt;script&gt;
CKEDITOR.replace("editor1", {});
&lt;/script&gt;
</code></pre>
