   <table>
     <colgroup> <col/> <col/> </colgroup>
     <tbody>
       <tr>

       <tr>
         <td>2</td>
         <td>
           <div class="content-wrapper">
             <p>
               <time datetime="2018-10-25"/> </p>
           </div>
         </td>
       </tr>
       <tr>
         <td>3</td>
         <td>
           <div class="content-wrapper">
             <p>
               <time datetime="2018-10-04"/> </p>
           </div>
         </td>
       </tr>
       <tr>
         <td>4</td>
         <td>
           <div class="content-wrapper">
             <p>
               <time datetime="2018-09-04"/> </p>
           </div>
         </td>
       </tr>
       <tr>
         <td colspan="1">5</td>
         <td colspan="1">
           <div class="content-wrapper">
             <p>
               <time datetime="2018-11-22"/> </p>
           </div>
         </td>
       </tr>
     </tbody>
   </table>
   <p>
     <br/>
   </p>
   <p>
     <br/>
   </p>
   
   

3. Try to sort the columns containing the dates

Expected Results

Table should be sorted correctly according to the date as it's when the user profile is in English

Actual Results

Dates are not sorted correctly.

Notes

Sorting works correctly when user profile is set to English
