CKEditor lose font when click outside editor and then clicks back to end of line

[Thiago]

Browser: Firefox 23.0.1 OS: Windows 7 Professional 32 bits

Note: This seems specific for Firefox, I was unable to reproduce it on IE.

Steps to reproduce:

1. Go to CKEditor (​http://ckeditor.com/demo#full)
2. Clear all existing content.
3. Select font Courier New (or any other available).
4. Type some content like "Today is Monday and I have a lot of things to fix".
5. Click outside the editor.
6. Click now at the right of last word typed ( in this case "fix").

The result: Current font (Courier new) is lost and editor returns to default "Font" option. This also occurs for font size.

After click outside the editor and click back.

This is caused by the fact that caret may be outside or inside span applying that font style. Firefox places it outside (however it sometimes chooses inside...), so after you click, the font is lost.

This issue is already reported, but I can't find the ticket now.
