Yes, indeed.

I tried running the code now (and commented out the
manual-html-fix-headers function), and I ended up with:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<!-- Created by GNU Texinfo 6.8, https://www.gnu.org/software/texinfo/ -->
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

This is with texi2any (GNU texinfo) 6.8. If I'm reading the code right,
the delete-region here is just deleting that <meta, the comment, and the
<title>.
It's probably different in every texinfo version, but altering the
(search-forward "</title>\n")
to
(search-forward "<title>")
should be safe in any case, so I'll go ahead and do that.

I think altering the HTML in this way isn't idea. It'd be much better
to just parse the HTML, alter the DOM (to remove/insert elements), and
then write the DOM out to HTML again. That'd be a whole lot less
brittle.
