AI Search tests is failing on next minor

It is failing here:

$this->assertSession()->pageTextContains('[Chocolate Cake](' . $this->nodes[0]->toUrl()->toString() . ')');

However, in Drupal 11.2, this is how the markup appears:

And in Drupal 11.3, this is how the markup appears:

I can't quite figure out where Drupal core has made a change that is effecting this. The actual value is missing completely, so the rendered item in 11.2 is:

<article>

  
      <h2>
      <a href="/node/1" rel="bookmark">
<span>Chocolate Cake</span>
</a>
    </h2>
    

      <footer>
      <article>
  <div class="js-form-item form-item js-form-type-item form-item- js-form-item- form-no-label">
        <h4 class="label">Member for</h4> 0 seconds
        </div>
</article>

      <div>
        Submitted by 
<span><span>ct7lb84o</span></span>
 on 
<span><time datetime="2025-09-02T07:29:43+10:00" title="Tuesday, 2 September 2025 - 07:29">Tue, 2 Sep 2025 - 07:29</time>
</span>
      </div>
    </footer>
  
  <div>
    
            <div><p>d53u1fapp20u9xclhptuqr7cm83p5cp5</p>
</div>
      
  </div>

</article>

And the rendered item in 11.3 is:

<article>

  
    

      <footer>
      <article>
  <div class="js-form-item form-item form-type-item js-form-type-item form-item- js-form-item- form-no-label">

    </footer>

So it is stripping out the H2 completely. I'll have more of a dig when I get time - perhaps somebody can glance at this and have an "aha" moment!

Depending on how much we "need" this to be correct, we could just add in a conditional or just check for the title? Dependant on this module's need for the check. I can't see anything that's "breaking" this, but I'd need some more time to dig in.
