Closed Issue: Pasting into source tab adds in non-breaking spaces [27940]

HtmlEditorExtender issue

Why, when i paste the following code into the source tab, then switch to the design view, and then back again, does the editor insert non-breaking spaces everywhere?

```
<table style="margin: 20px auto; width: 640px;">
<tbody>
<tr>
<td>
<a href="http://www.website.com" title="" target="_blank">
<img src="http://www.website.com/Images/imagefile.png" style="width: 100%;" alt="ALT" /></a>
</td>
</tr>
<tr>
<td style="font-family: arial,helvetica,sans-serif; color: #282828; font-size: 16px; padding: 20px;">
