Unlink in Firefox leaves a span-tag if style or class attributes are set

[Niklas Nilsson]

If a link has a class or style attribute, unlinking in Firefox 4.0 will leave a span tag behind with the same class/style attributes.

Steps to reproduce:

1. In source mode, enter

   <a class="class" href="#" style="font-weight:bold;">Test</a>
   

2. Switch back to WYSIWYG
3. Select the text
4. Click unlink
5. Go to source mode, HTML is now

   <span class="class" style="font-weight:bold;">Test</span>

This happens in Firefox and Opera.

Opera behaves a little different:

1. When selecting whole link or placing cursor behind letter "t" and using "unlink" it produces:

   Test<a class="class" href="#" style="font-weight:bold;"><span style="display: none">&nbsp;</span></a>
   

2. When placing cursor before "T" unlink option doesn't work
3. When placing cursor inside word "Test" it produces

   T<span style="display: none">&nbsp;</span>est
