                                        </div>
                                        I have this code in a block:<br>
                                        <br>
                                        &lt;div id="headcontact"&gt;<br>
                                        &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;

                                          moz-do-not-send="true"
                                          href="mailto:mail@mail.org"
                                          target="_blank">mail@mail.org</a>"&gt;<a
                                          moz-do-not-send="true"
                                          href="mailto:mail@mail.org"
                                          target="_blank">mail@mail.org</a>&lt;/a&gt;&lt;/li&gt;&lt;li&gt;&lt;em
                                        class="mini-ico-user"&gt;&lt;/em&gt;
                                        (999) 463 1234&lt;/li&gt;<br>
                                        &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/ul&gt;<br>
                                        &nbsp;&nbsp;&nbsp; &lt;/div&gt;<br>
                                        <br>
                                      </div>
                                      I close the block after editing
                                      and the em tag can be seen in
                                      firebug and it works as intended.
                                      I am using css transitions and
                                      glyphicons. <br>
                                      <br>
                                    </div>
                                    Then I go into the editor and I see
                                    <br>
                                    <br>
                                    &lt;div id="headcontact"&gt;<br>
                                    &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &lt;ul&gt;<br>
                                    &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &lt;li&gt;<br>
                                    &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &lt;a href="mailto:<a
                                      moz-do-not-send="true"
                                      href="mailto:mail@mail.org"

                                      moz-do-not-send="true"
                                      href="mailto:mail@mail.org"
                                      target="_blank">mail@mail.org</a>&lt;/a&gt;&lt;/li&gt;<br>
                                    &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &lt;li&gt;<br>
                                    &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; (999) 463
                                    1234&lt;/li&gt;<br>
                                    &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &lt;/ul&gt;<br>
                                    <br>
                                  </div>
                                  No more em tags! And the intended
                                  appearance of the icons doesn't work.
                                  <br>
                                  <br>
                                </div>
                                I tried using the wysiwyg module with
                                ckeditor and the ckeditor module by
                                itself adding config.allowedContent =
                                true; to the ckeditor.config.js file.
                                And to the advanced options.<br>
                              </div>
                              I don't have the html filter on. <br>
                              <br>
                            </div>
                            Any ideas as to a solution to stop it from
                            stripping the tags?<br>
