So we pass "<p><b><i><u></p><p>X" but not <p><b><i><u></p> <p>X" it seems.
Given that the latter actually does generate:

<html>
    <head>
    <body>
      <p>
        <b>
          <i>
            <u>
      " "
      <p>
        <b>
          <i>
            <u>
              "X"

as you seem to suggest.

Ok, I'll rewrite our algorithm to match that and see if it helps, thanks!
