Here's a test case:

This post ist testing whether Moodle issue MDL-32114(https://tracker.moodle.org/browse/MDL-32114#add-comment) is still relevant. Note that the quote below must at least have a blank line when the indent level is reduced again. So let's test a quote:

> This is a small quote.
>
> In it, we quote something more:
> > This is a 2nd-level quote.

> Back on level 1.Markdown preview shows that CSS does not consider quotes at all!

So, let's test with some ```code snippet``` whether carrets are now correctly processed:
```
C++
#include <iostream>int main() {
  std::cout << "Hello world!" << std::endl;
  return 0;
}
```
Here we are trying some more nasty things:<p>You were looking for:<script type="text/javascript">alert("XSS")</script></p>

<iframe src="javascript:alert('vulnerable');">kou</iframe>

Lorem ipsum and some more with a <button.onclick="alert(String.fromCharCode(60,115,99,114,105,112,116,62,97,108,101,114,116,40,34,67,114,111,115,115,83,105,116,101,83,99,114,105,112,116,105,110,103,64,82,69,77,79,86,69,34,41,60,47,115,99,114,105,112,116,62));">String:fr
om.Char.Code</button> to click.
