title: How do you insert HTML into a text node in AngleSharp?
body: <p>I'm parsing a document with AngleSharp.  I have a text node (NodeName: "#text") and I want to insert some HTML in it.  I can certainly reset NodeValue to whatever I want, but it's still a text node, so all the brackets are escaped.</p>
  
  <p>How do I take the string value of a text node, inject some HTML into it, then have a parsed DOM representation that that HTML take the place of the original text node?</p>
