Steps to reproduce:
1. Go to midas demo: http://www.mozilla.org/editor/midasdemo/
2. Enter the following HTML:
<table border="1"><tbody><tr><td>one</td><td>two</td></tr><tr><td><br></td><td><br></td></tr></tbody></table>
3. Select the entire top row of the table and copy.

4a. Click on the first cell of the second table row and paste. A new table is created inside the cell like this:
<table border="1"><tbody><tr><td>one</td><td>two</td></tr><tr><td><span class="Apple-style-span" style="-webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; "><table border="1"><tbody><tr><td>one</td><td>two</td></tr></tbody></table></span></td><td><br></td></tr></tbody></table>

4b. After step 3, select the entire second row and paste. A new table is created BELOW the original table, leaving the second row of the first table empty:
<table border="1"><tbody><tr><td>one</td><td>two</td></tr><tr><td><br></td><td><br></td></tr></tbody></table><table border="1"><tbody><tr><td>one</td><td>two</td></tr></tbody></table><br>

Expected result: second row of table should be replaced by content from first row, like this:
<table border="1"><tbody><tr><td>one</td><td>two</td></tr><tr><td>one</td><td>two</td></tr></tbody></table>
