<p>I'm getting an error on admin taxonomy page where vocabularies are listed.</p>
<p><code>User error: "termcase" is an invalid render array key in Drupal\Core\Render\Element::children() (line 98 of /var/www/html/web/core/lib/Drupal/Core/Render/Element.php). =></code></p>
<p>- which is repeated/logged 10 times (appears as it is triggered twice per existing vocabulary as I currently have 5 different vocabularies.) with just that error listed, no other details.</p>
<p>On the vocab list page the following stack info is repeated 10 times (not sure if it will be useful)..</p>

Also tested to make sure it works when adding a new term through an autocomplete term reference field on a content type and it does also without error.</p>
<p>As near as I can tell there are no other issues that I'm seeing..</p>
<p>For good measure I'm currently working with Drupal 10.2.3 on Apache 2.4.38 running PHP 8.1.13</p>
