Problem description

When I add a code block to the editor with some random code or text, and save it, the resultant HTML has two extra </pre> and </code> tags.

For example, writing this:

Gets stores like this in my database:

<pre><code class="hljs javascript"><span class="hljs-keyword">const</span> a = <span class="hljs-number">123</span>;</code></pre></code></pre>

Expected behavior

That the output would contain just one set of closing tags, not two.

Steps to reproduce

1. Try creating an Article and add some text to it, and save it.
2. Inspect the stored output.

I've tracked this down to a bug in the DOMSerializer in the tiptap-php package. Not much that can be done at this point.

Oh, I'll raise this issue in tiptap-php then, @awcodes. Thanks a lot for checking this out!
