When you use insertAdjacentHTML to insert HTML code containing <script> tags into the DOM, the <script> tags will not be executed. This behavior is similar to using innerHTML, where <script> elements inserted do not execute when they are inserted12.

If you want to execute scripts dynamically, you would need to create a new <script> element and append it to the DOM. Here’s an example of how you can do this:

これは、これは間違っている可能性が高い。createContextualFragmentを使って
<script>を含むHTMLを作りInsertしてみたら、<script>は実行された。
さらに、DOMContentLoadedのイベントからcreateContextualFragmentを使って
<script>を含むHTMLを作りInsertしてみたら、<script>は実行された。
