Razor removes invalidly named HTML elements from output.

[NTaylorMullen]

Typing the following invalid HTML snippets:

<<p>
</  <<p>
< < /<  <p>

results in

<p>

This is because the TagHelperParseTreeRewriter ignores no tag name HTML elements and doesn't place them back onto the syntax tree when rewriting it (doesn't matter if you have tag helpers in your app).
