In HTML mode, \listoffigures and \listoftables do not render properly

[bluegate010]

When rendering in HTML, an input file that declares:

    \tableofcontents
    
    \listoffigures
    
    \listoftables
    
    # Heading
    
    ```mermaid {caption="Flowchart" #fig:flowchart}
    graph TD;
        A-->B;
    ```
    
    +-----------+------------+
    | First col | Second col |
    +===========+============+
    | One       | Two        |
    +-----------+------------+
    
    Table: Example table {#tbl:example-table}

with a template that contains:

    <h1>Table of contents</h1>
    <nav class="toc">
    $table-of-contents$
    </nav>
    <article>
    $body$
    </article>

will render as:

    <h1>Table of contents</h1>
    <nav class="toc">
    <ul>
    <li>List of Figures</li>
    <li>List of Tables</li>
    <li><a href="#heading" id="toc-heading">Heading</a></li>
    </ul>
    </nav>
    <article>
    <h1>List of Figures</h1>
    <div class="list list-of-fig">
    1. Flowchart<br />
    
    </div>
    <h1>List of Tables</h1>
    <div class="list list-of-tbl">
    1. Example table<br />
    
    </div>
    <h1 id="heading">Heading</h1>
    ...

The entries in the list of figures and tables are not rendered as links, and the "List of Figures" / "List of Tables" entries in the table of contents are not rendered as links either.

As a temporary workaround, the \listoffigures and \listoftables directives are currently filtered out in build.sh when rendering HTML output.
