I have a dojo here to demonstrate the issue.
https://dojo.telerik.com/@smilelari/ejUtax/2
When the text in the textarea is set to html that contains styling (like: <style type="text/css">.cs2654AE3A{text-align:left;text-indent:0pt;margin:0pt 0pt 0pt 0pt} .csC8F6D76{color:#000000;background-color:transparent;font-family:cursive;font-size:15pt;font-weight:normal;font-style:normal;}</style><p class="cs2654AE3A"><span class="csC8F6D76">Hello</span></p>), if you select text and then select a format from the format menu, the format (for example Heading 1) is not applied. Any ideas how to fix this? Thanks
