Description

What happened?

This code will throw error (note the "tag" Twig tag placed inside "nav").

{% set entries = craft.entries().section('pages').all() %}

<ul id="nav">
{% nav entry in entries %}

{% tag 'div' with {
   class: 'something',
} %}
some content 
{% endtag %}

    <li>
      <a href="{{ entry.url }}">{{ entry.title }}</a>
      {% ifchildren %}
        <ul>
          {% children %}
        </ul>
      {% endifchildren %}
    </li>
  {% endnav %}
</ul>

Start by reproducing the reported template in Craft CMS 4.4.13, focusing on the interaction between the nested nav and tag Twig tags. Locate the relevant template-processing entry point and determine what regression coverage exists; done means the nested tags render without the reported error.
