sourcelink element broken in version 0.16.1

[ukukas]

In version 0.16.1 the sourcelink element gets rendered as follows:

<div class="sidebar-secondary-item">
  <div role="note" aria-label="source link">
    <h3>This Page</h3>
    <ul class="this-page-menu">
      <li><a href="../_sources/index.md.txt" rel="nofollow">Show Source</a></li>
    </ul>
   </div>
</div>

Reverting back to version 0.16.0 appears to fix the issue:

<div class="sidebar-secondary-item">
  <div class="tocsection sourcelink">
    <a href="../_sources/index.md.txt">
      <svg class="svg-inline--fa fa-file-lines" aria-hidden="true" focusable="false" data-prefix="fas" data-icon="file-lines" role="img" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 384 512" data-fa-i2svg=""><path fill="currentColor" d="M64 0C28.7 0 0 28.7 0 64V448c0 35.3 28.7 64 64 64H320c35.3 0 64-28.7 64-64V160H256c-17.7 0-32-14.3-32-32V0H64zM256 0V128H384L256 0zM112 256H272c8.8 0 16 7.2 16 16s-7.2 16-16 16H112c-8.8 0-16-7.2-16-16s7.2-16 16-16zm0 64H272c8.8 0 16 7.2 16 16s-7.2 16-16 16H112c-8.8 0-16-7.2-16-16s7.2-16 16-16zm0 64H272c8.8 0 16 7.2 16 16s-7.2 16-16 16H112c-8.8 0-16-7.2-16-16s7.2-16 16-16z"></path></svg><!-- <i class="fa-solid fa-file-lines"></i> Font Awesome fontawesome.com --> Show Source

</div>

I do not see any changes to components/sourcelink.html so unsure what could be causing this.

The behavior remains the same when the sourcelink element is moved to the header or footer.

Hi there @ukukas do you have a link to your project?

I just checked our documentation and I can see the source links properly rendered, for example for https://pydata-sphinx-theme.readthedocs.io/en/stable/user_guide/index.html

<a href="../_sources/user_guide/index.md">
      <svg class="svg-inline--fa fa-file-lines" aria-hidden="true" focusable="false" data-prefix="fas" data-icon="file-lines" role="img" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 384 512" data-fa-i2svg=""><path fill="currentColor" d="M64 0C28.7 0 0 28.7 0 64V448c0 35.3 28.7 64 64 64H320c35.3 0 64-28.7 64-64V160H256c-17.7 0-32-14.3-32-32V0H64zM256 0V128H384L256 0zM112 256H272c8.8 0 16 7.2 16 16s-7.2 16-16 16H112c-8.8 0-16-7.2-16-16s7.2-16 16-16zm0 64H272c8.8 0 16 7.2 16 16s-7.2 16-16 16H112c-8.8 0-16-7.2-16-16s7.2-16 16-16zm0 64H272c8.8 0 16 7.2 16 16s-7.2 16-16 16H112c-8.8 0-16-7.2-16-16s7.2-16 16-16z"></path></svg><!-- <i class="fa-solid fa-file-lines"></i> Font Awesome fontawesome.com --> Show Source

Actually, this is a duplicate of #2088 so I am closing this as a duplicate
