Corrected valid code, what to do?

Valid HTML:

<a href="#" class="list-group-item">
<h4 class="list-group-item-heading">List group item heading</h4>
<p class="list-group-item-text">Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.</p>
</a>

Сhanges to:

<h4 class="list-group-item-heading"><a class="list-group-item" href="#">List group item heading</a></h4>

<p class="list-group-item-text"><a class="list-group-item" href="#">Donec id elit non mi porta gravida at eget metus. Maecenas sed diam eget risus varius blandit.</a></p>

Please help configure editor.
