When deleting the second ordered list items in a table cell, which entire content is a contenteditable area, its content is merged with the first list item:

Before:
| <table>
|   border="1"
|   <tbody>
|     <tr>
|       <td>
|         <div>
|           contenteditable="true"
|           <ol>
|             <li>
|               "a"
|             <li>
|               id="li"
|               "<#selection-caret>|b"

After:
| <table>
|   border="1"
|   <tbody>
|     <tr>
|       <td>
|         <div>
|           contenteditable="true"
|           <ol>
|             <li>
|               "a<#selection-caret>|b"
