As a stop-gap, I created a quick & dirty BeautifulSoup-based plugin that adds title attributes to h1..h6 entries. (It doesn't check the TOC and it doesn't merge successive h1..h6 entries.)

It changes:

<h1 id="toc_marker-26">21</h1>

    <h2><span class="Cap">E</span><span class="SmallCap">N CHEMIN POUR</span> <span class="Cap">S</span><span class="SmallCap">HADAR</span> <span class="Cap">L</span><span class="SmallCap">OGOTH</span></h2>

to:

 <h1 id="toc_marker-26" title="21">21</h1>
  <h2 title="En chemin pour shadar logoth"><span class="Cap">E</span><span class="SmallCap">N CHEMIN POUR</span> <span class="Cap">S</span><span class="SmallCap">HADAR</span> <span class="Cap">L</span><span class="SmallCap">OGOTH</span></h2>

You can download it from my Dropbox.

The plugin code is:

Spoiler:

def run(bk):

    # process all files
    for html_id, href in bk.text_iter():
        html = bk.readfile(html_id)
        file_name = os.path.basename(href)
        soup = BeautifulSoup(html, 'html.parser')
        orig_soup = str(soup)

        # process all headings
        headings = soup.find_all(['h1', 'h2', 'h3', 'h4', 'h5', 'h6'])
        for heading in headings:
            title = heading.get_text().strip()
            title = title.lower().capitalize() # ABC DEF > Abc def
            #title = title.title() # ABC DEF > Abc Def
            if title != '':
                heading['title'] = title

        # update html if the code was changed
        if str(soup) != orig_soup:
            bk.writefile(html_id, str(soup.prettyprint_xhtml(indent_level=0, eventual_encoding="utf-8", formatter="minimal", indent_chars="  ")))
            print('{} updated.'.format(file_name))

    return 0

For English books, change the following section:

            title = title.lower().capitalize() # ABC DEF > Abc def
            #title = title.title() # ABC DEF > Abc Def

to:

            #title = title.lower().capitalize() # ABC DEF > Abc def
            title = title.title() # ABC DEF > Abc Def
