Switching from HTML to Visual editor removes paragraphs after line breaks inside TABLES

[RustyBadRobot]

Empty paragraphs between line breaks inside a TABLE are removed when switching editor mode from HTML to Visual:

<table>
<tbody>
<tr>
<td>Line 1
Line 2

&nbsp;

Line 3
Line 4</td>
</tr>
</tbody>
</table>

After switching between Text / Visual becomes:

<table>
<tbody>
<tr>
<td>Line 1
Line 2&nbsp;

Line 3
Line 4</td>
</tr>
</tbody>
</table>

Then after another switch becomes:

<table>
<tbody>
<tr>
<td>Line 1
Line 2Line 3
Line 4</td>
</tr>
</tbody>
</table>

Hi and thanks for the report!

This is an old, known bug tracked in #20943. That ticket suggests a plugin to work around it.
