non list content being typeset as lists

[StephDriver]

This has been split from #4244 as it relates to typesetting, while the rest of that was template work.

misused list example:

a poem that should be written in a blockquote, instead has been marked-up as an unordered list.

<ul class="list-simple">
<li><p>That Night a Fire did break out—</p></li>
<li><p>You should have heard Matilda Shout!</p></li>
<li><p>You should have heard her Scream and Bawl,</p></li>
<li><p>And throw the window up and call</p></li>
<li><p>To People passing in the Street—</p></li>
<li><p>(The rapidly increasing Heat</p></li>
<li><p>Encouraging her to obtain</p></li>
<li><p>Their confidence)—but all in vain!</p></li>
<li><p>For every time she shouted ‘Fire!’</p></li>
<li><p>They only answered ‘Little Liar!’”</p></li>
</ul>```
