Language dropdown menu on mobile: paths default to locale homepage not translations of current page #2131
Description
Consider https://opentelemetry.io/docs/what-is-opentelemetry/, the top-nav language dropdown menu is:
<ul class="dropdown-menu">
<li><a class="dropdown-item" href="/pt/docs/what-is-opentelemetry/">Português</a></li>
<li><a class="dropdown-item" href="/ja/docs/what-is-opentelemetry/">日本語 (Japanese)</a></li>
<li><a class="dropdown-item" href="/fr/docs/what-is-opentelemetry/">Français</a></li>
<li><a class="dropdown-item" href="/es/docs/what-is-opentelemetry/">Español</a></li>
<li><a class="dropdown-item" href="/zh/docs/what-is-opentelemetry/">中文 (Chinese)</a></li>
</ul>The same menu on mobile, which appears in the side-nav under the hamburger, is like this when sidebar_cache_limit is set to a very low number, like 1:
<ul class="dropdown-menu">
<li><a class="dropdown-item" href="/fr/docs/">Français</a></li>
<li><a class="dropdown-item" href="/es/docs/">Español</a></li>
<li><a class="dropdown-item" href="/pt/docs/">Português</a></li>
<li><a class="dropdown-item" href="/ja/docs/">日本語 (Japanese)</a></li>
<li><a class="dropdown-item" href="/zh/docs/">中文 (Chinese)</a></li>
</ul>Notice that the paths all point to the locale's landing page. It might have to do with caching of partials?
