Textarea HTML in highlight / Admin panel

I found a bug while writing a page with the code highlighting feature in the Admin panel. I wanted to write some example code with html code: a doctype, a head, a form, a textarea tag and showing how to integrate CKEditor in that hmtl page.

But when I write the markdown:

<!doctype html>
  <meta charset="utf-8">
    <title>CKEditor integreren</title>
    <script src="ckeditor/ckeditor.js">
  <textarea name="message" id="editor1" cols="30" rows="10"></textarea>

The Admin text form stops at the closing textarea tag in the markdown. The page shows up perfect when you visit the page thought… It’s just de admin panel that’s treating it funky. Screen Shot 2015-08-19 at 13

Hmmm… this is an odd one. Can you create an issue in the admin plugin issue tracker and put all the details in it? https://github.com/getgrav/grav-plugin-admin/issues
