renderFromHTML duplicates nested lists content #121
Description
Hi,
renderFromHTML duplicates lists content in the editor.
Here is an example to reproduce the error.
I hope this helps to fix the bug.
<script src="https://cdn.jsdelivr.net/npm/@editorjs/editorjs@latest"></script>
<script src="https://cdn.jsdelivr.net/npm/@editorjs/list@latest"></script>
...
editor.blocks.renderFromHTML(`<div>
<ul>
<li>David 1
<ul>
<li>Bulletpoint 1.A</li>
<li>Bulletpoint 1.B</li>
</ul>
</li>
<li>Erica 2
<ul>
<li>Bulletpoint 2.A</li>
<li>Bulletpoint 2.B</li>
</ul>
</li>
</ul>
</div>`);
Should be like this
