Using unescaped html closing tags body, html or div causes the preview to break

[DemonTPx]

When adding </body>, </html> or </div> to my document, the preview of the document breaks.

The </body> and </html> tags just stop the output of the rest of the document and </div> causes it to lose its style (the white background changes to gray and it seems that the markdown is no longer parsed.)
