Converted @multitable displays as empty

[Eli Zaretskii]

Please take a look at this node from the Emacs's Flymake manual:

  
https://www.gnu.org/software/emacs/manual/html_mono/flymake.html#Mode-line-status

It displays as (almost) empty.  But the page source reveals that we
have a <table> there:

  <p>The following statuses are defined:
  </p>
  <table>
  <tr><td width="25%">[<var>nerrors</var> <var>nwarnings</var> ...]</td><td 
width="75%">Normal operation. <var>nerrors</var> and <var>nwarnings</var> are, 
respectively,
  the total number of errors and warnings found during the last buffer
  check, for all backends. They may be followed by other totals for
  other types of diagnostics (see <a href="#Flymake-error-types">Customizing 
Flymake error types</a>).</td></tr>
  <tr><td width="25%"><code>Wait</code></td><td width="75%">Some Flymake 
backends haven&rsquo;t reported since the last time they
  where questioned.  It is reasonable to assume that this is a temporary
  delay and Flymake will resume normal operation soon.</td></tr>
  <tr><td width="25%"><code>!</code></td><td width="75%">All the configured 
Flymake backends have disabled themselves: Flymake
  cannot annotate the buffer and action from the user is needed to
  investigate and remedy the situation (see <a 
href="#Troubleshooting">Troubleshooting</a>).</td></tr>
  <tr><td width="25%"><code>?</code></td><td width="75%">There are no 
applicable Flymake backends for this buffer, thus Flymake
  cannot annotate it.  To fix this, a user may look to extending Flymake
  and add a new backend (see <a href="#Extending-Flymake">Extending 
Flymake</a>).</td></tr>
  </table>

For some reason, this table, which AFAICT is the result of converting
@multitable to HTML, displays as empty in several browsers (Firefox,
Chrome).  Can you please advise what is wrong with this table and how
to fix this?

Thanks.
