The second (and further) table on a page doesn't honour alignment in header

[sdruskat]

The alignment in table headers seems broken for some cases where you have more than one table per file.

This seems to be an issue with markdown parsing, as the respective HTML tag elements aren't written (source from the rendered last example):

<p>Test 4 Table 1 (mixed headers)</p>
<table>
    <thead>
        <tr>
            <th align="left"> left </th>
            <th align="right"> right </th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td align="left"> Long text value </td>
            <td align="right"> Long text value </td>
        </tr>
    </tbody>
</table>
<p>Test 4 Table 2 (mixed headers)</p>
<table>
    <thead>
        <tr>
            <th> left </th>
            <th> right </th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td align="left"> Long text value </td>
            <td align="right"> Long text value </td>
        </tr>
    </tbody>
</table>
