Tableselect checkbox and radio buttons do not function properly

Regular checkboxes and radio buttons work fine, but when they are inside of a tableselect element they do not render properly.
I traced the issue down to an extra div being wrapped around the radio/checkbox element. To fix the problem either the label wrapper has to have content aside from the input:
<label for="xyz"><input type="radio" id="xyz" name="xyz"></label>
would need to be
<label for="xyz"><input type="radio" id="xyz" name="xyz"> XYZ</label>

But this messes up the view of the table select. Removing the extra div tag should work though.
Instead of this:

<div>
  <td>
    <label for="example-radio-button"> <input type="radio" id="example-radio-button name="example-radio-button" value="example_radio" class="form-radio"></label> 
  </td>
</div>

It should output this:

<td>
 <label for="example-radio-button"> <input type="radio" id="example-radio-button name="example-radio-button" value="example_radio" class="form-radio"> </label>
</td>
