Markdown code block html entities

Hello, thanks for this great tool!
I just have a problem using markdown code blocks in overview page. < gets replaced by `&lt;`
E.g.
```
<!DOCTYPE html>
<html lang="lv">
...
</html>
```
when generated, is shown as
```
&lt;!DOCTYPE html&gt;
&lt;html lang="lv"&gt;
...
&lt;/html&gt;
```
Any ideas how could i fix this?
