jQuery Mobile 1.4.5 Table Reflow

jQuery Mobile 1.4.5 Table Reflow

If I follow the example in the jQuery Mobile 1.4.5 demos for Table Reflow, but set up my table using thead:
<table>
<thead>
<tr><th></th>...</tr>
</thead>
<tbody>
<tr><td></td>...</tr>
</tbody>
</table>

Then I don't get any column headers (labels) moved down in the reflow process. I only get data, when headers are supposed to be displayed left of the data.

If I use a "old" table, then everything works:
<table>
<tr><th></th>...</tr>
<tr><td></td>...</tr>
</table>

Isn't Table Reflow supposed to also work for thead/tbody tables?
