Fixes #2996.

An easy fix, we were simply missing a call to this.escape_html. To be honest, I'm surprised this hasn't been a reported issue yet.

As a bonus, there are even tests for red-greening the fix!

Many thanks to @cade for his assistance with figuring out was was going on in the Ancient Technology™ test (read: Prototype JS).

I’m 👍🤘 — I assume you’ve double-checked for double-escaping, but that would be my only concern.

Quick note: this uses the idiom `div.innerHTML = tmpl` instead of what we've
been using in our other tests, which is `div.update(tmpl)` because of some fun
stuff that Prototype does when one calls `update`:

docs: http://api.prototypejs.org/dom/Element/prototype/update/

Relevant quote for funsies:

> If newContent is a string and contains one or more inline <script>
> tags, the scripts are scheduled to be evaluated after a very brief pause
> (using Function#defer) to allow the browser to finish updating the DOM.

Yeah.
