Spurious <div>-within-<p> produced in html output when multiple authors are present

When multiple authors are present for a #language scribble/base document, the html renderer produces bogus <div class="SIntrapara">s within a <p> after the pre-title content and before the post-title content.

This presents two problems. First, the <div class="SIntrapara">s don't seem to serve any function. Perhaps they were intended to separate the authors, and the authors from subsequent content? But the authors are already separated by <span class="SAuthorSep">.

Second, as a block-level element, a <div> is not permitted within a <p>. The <p> is added in the overridden render-compound-paragraph method in html-render.rkt. I don't understand the purpose of wrapping a Scribble compound-paragraph in a <p> tag, as other occurrences of compound-paragraph can end up introducing both <div class="SIntrapara"> and other block-level tags such as <blockquote> within the <p> tag, which again, is not permitted by the html spec.

In the example html output I'm attaching, I've run Scribble's output through html-tidy reflow to make it readable.

Hmm, attaching files of type .scrbl and .rkt are not allowed. I'll add them as text in separate comments.

Start in html-render.rkt at the overridden render-compound-paragraph method, then reproduce the multiple-author Scribble example and inspect the generated HTML. Determine how the pre-title and post-title content is wrapped; done means the output no longer places div elements inside p elements while preserving the author separators and surrounding content.
