Unexpected bold when breaking a line after Removing Format on collapsed selection

[Olek Nowodziński]

1. Use replacebycode sample.
2. Set HTML

   <p><b>Apollo 11</b> was the spaceflight that landed the first humans.</p>
   

3. Set caret so it is still bold

   Apollo 11^ was…
   

4. Click remove format.
5. Type a few words.
6. ENTER.
7. For unknown reason, typing bold in the new line:

   <p><b>Apollo 11</b> cow says moo</p>
   
   <p><b>...</b> was the spaceflight that landed the first humans.</p>
   

I'm able to reproduce it since 3.6.6.1 in Chrome, Firefox and Safari (Mac).

When you have something like <p><strong>Apollo 11</strong> was the spaceflight that landed the first humans.</p> and then use Remove Format command, below line with Apollo 11 new empty set of strong tags is created <strong></strong>.

These tags then get transferred to new paragraph when you press enter. FireBug shows this nicely.

I was able to reproduce this problem from CKEditor 3.5.1 rev. [6288]. It seems that remove format for collapsed selection was introduced then.
