Deleting &nbsp; following <br /> , deletes the break tag.

We are expiriencing som strange behavior using the source editing mode.

Setup

• version 4.1.1
• fullPage:true
• config.enterMode = CKEDITOR.ENTER_BR

Issue

In source edit mode when deleting a &nbsp; that are directly followed by a <br /> tag, it is the <br /> tag that are deleted when togling source mode.

To reproduce

•  use the attached content as editor content.
• Switch to source view
• delete the &nbsp; placed befor the <h3> tag
• Switch to wyciwyg mode and then back to source
• Now the <br /> tag that where placed before the deleted &nsbp; is gone, but the &nbsp; is back
• If you delte the &nbsp; again the next <br /> tag is removed

Can you give os an estimate to when this bug will be fixed.
