[Parchment] Maximum optimize iterations when creating Table blots

I am trying to understand how blots work and I wanted to recreate step by step the Table example from the parchment repo. For now I wrote the following code:

import Quill from 'quill';
import { ContainerBlot } from 'parchment';

class TableBody extends ContainerBlot {}
TableBody.blotName = 'table-body';
TableBody.tagName = 'TBODY';

class Table extends ContainerBlot {}
Table.tagName = 'TABLE';
Table.blotName = 'table-container';
Table.allowedChildren = [TableBody];

Quill.register(Table, true);

and the main node on which Quill is instantiated has the following content:

<table>
    <tbody>
        <tr>
            <th><b>Title</b></th>
        </tr>
        <tr>
            <td >
                  Some row
            </td>
        </tr>
    </tbody>
</table>

and I get the following error:

bundle.js:231739 Uncaught Error: [Parchment] Maximum optimize iterations reached

Steps for Reproduction
