HTML Table does not render if there's blank line inside markup

[d4nyll]

Current behavior

Given the following input:

<table>
  <thead>
    <tr>
      <th>Header 1</th>
      <th>Header 2</th>
      <th>Header 3</th>
    </tr>
  </thead>
  
  <tbody>
    <tr>
      <td>Field 1</td>
      <td>Field 2</td>
      <td>Field 3</td>
    </tr>
  </tbody>
</table>

<table>
  <thead>
    <tr>
      <th>Header 1</th>
      <th>Header 2</th>
      <th>Header 3</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Field 1</td>
      <td>Field 2</td>
      <td>Field 3</td>
    </tr>
  </tbody>
</table>

I am getting the following preview:

Only the second table renders properly. The first table does not render properly.

Expected behavior

Both tables to render correctly.

Steps to reproduce

1. Create a new Markdown Note
2. Paste the above markup in the editor

The bug is due to CommonMark (HTML-Block condition 6) which markdown-it is following at the letter.
remark doesn't suffer from this issue. So it should be fixed when #1563 is done.
