title: Passing variables with include statement in Jinja2 template
body: <p>I have a html file containing the following snippet of code in Jinja2 templating language.</p>
  
  <pre><code>{% block head %}
      {{ super() }}
      {% with textarea="txtMessageContent" %}
          {% include "vvv/vvv/TinyMCE.html" %}
      {% endwith %}
  {% endblock %}
  </code></pre>
  
  <p>I am trying to pass the variable textarea to the TinyMCE.html template which contains the following code. </p>
  
  <pre><code>{% block InitTinyMCE %}
  &lt;script src="https://x.x.x/x/js/jquery-2.1.0.min.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="/static/js/tinymce/tinymce.min.js"&gt;&lt;/script&gt;
  &lt;script type="application/javascript"&gt;
  alert(textarea);
      $(document).ready(function (textarea){
          tinymce.init({
              selector: textarea,
              menubar: true,
              plugins: "hr code preview",
              content_css:"https://x.x.x/x/css/backend-boostrap.css",
              remove_linebreaks: false,
              convert_newlines_to_brs: true
          });
      });
  &lt;/script&gt;
  {% endblock %}
  </code></pre>
  
  <p>When I load the page I see that the variable is not being passed throught. I can confirm this due to the following error. </p>
  
  <p>textarea is not defined. </p>
