Why when I change the header active and passed class is not added when the left toc-item is clicked?

[Julia-Lm]

Why when I change header and add custom styles the "md-nav__link--passed" and "md-nav__link--active" classes is not added when the left toc-item is clicked, but add this classes to prev toc-item element, if it is?

I use mkdocs-material-9.5.8 version.

Maybe I need use to specify a minimum height that the header should be in order for the code to add these classes to work correctly?

my header.html:

<!-- Determine base classes -->
{% set class = "md-header" %}
{% if "navigation.tabs.sticky" in features %}
  {% set class = class ~ " md-header--shadow md-header--lifted" %}
{% elif "navigation.tabs" not in features %}
  {% set class = class ~ " md-header--shadow" %}
{% endif %}

<!-- Header -->
<header class="{{ class }}" data-md-component="header">
  <nav
    class="md-header__inner md-grid"
    aria-label="{{ lang.t('header') }}"
  >

    <!-- Link to home -->
    <div class="md-header-home-link">
      <a
        href="{{ config.extra.homepage | d(nav.homepage.url, true) | url }}"
        title="{{ config.site_name | e }}"
        class="md-header__button md-logo"
        aria-label="{{ config.site_name }}"
        data-md-component="logo"
      >
        {% include "partials/logo.html" %}
      </a>
    </div>
    
    <div class="md-header-content">
      <!-- Navigation tabs (sticky) -->
      {% if "navigation.tabs.sticky" in features %}
      {% if "navigation.tabs" in features %}
          {% include "partials/tabs.html" %}
      {% endif %}
      {% endif %}
      <!-- Button to open drawer -->
      <label class="md-header__button md-icon" for="__drawer">
        {% include ".icons/material/menu" ~ ".svg" %}
      </label>
    

      <!-- Button to open search modal -->

      <label class="md-header__button md-icon" for="__search">
          {% include ".icons/material/magnify.svg" %}
        </label>

        <!-- Search interface -->
        {% include "partials/search.html" %}

        <!-- Link to # -->
        <a
        href="#"
        title="#"
        class="md-header__link md-link"
      >
        Go to #
      </a>

            {% set scheme = option.scheme | d("default", true) %}
            <input
              class="md-option"
              data-md-color-media="{{ option.media }}"
              data-md-color-scheme="{{ scheme | replace(' ', '-') }}"
              data-md-color-primary="{{ option.primary | replace(' ', '-') }}"
              data-md-color-accent="{{ option.accent | replace(' ', '-') }}"
              {% if option.toggle %}

Hi, i am sorry but I don't quite understand the question you are asking. Before entering into a discussion, though, can I ask if the header.html is from the same version of Material for MkDocs that you are using to build? Customizations made with one version can stop working if a template or partial changes, so it would be important to rule this out as a cause.

If this is not the cause then to help we would need to see in a screenshot what the undesired behaviour is and to get a minimal reproduction that would allow us to investigate the probem on our machines.

The header.html doesn't look like it's from the current version, as the "tabs" logic is a bit different.
Also if the issue is with md-nav__link--passed then the JavaScript responsible for changing the classes doesn't work, so I would check the developer tools in the browser to see if there are any errors in the console.
