Steps to reproduce:
Search for e.g. "css max-lines" or any other result which shows a StackOverflow widget, where the StackOverflow result will contain a runnable code snippet (see: https://stackoverflow.blog/2014/09/16/introducing-runnable-javascript-css-and-html-code-snippets/ )
The result will then contain some StackOverflow-internal HTML comments, that are not actually part of the answer, as readable text of the result.
I marked them in the screenshot with red so it's clear what I talk about.
Expected behaviour:
Either actually runnable snippet, or HTML comments concerning the snippet runner at least hidden.
