Path not refreshed in Firefox and Webkit

[Jakub Ś]

1. Open sample page
2. Select sample text and apply "blue heading" to it.
3. Delete whole text
4. Press backspace button few more times to remove formatting
5. Start typing.

Result:
Firefox and Webkit- Path is showing “body h3” but the typed letters are small. If you change to source view you will see that there is no “h3” only “p”. This hasn't worked form CKEditor 3.5.3 rev [6586].

IE and Opera – the path is not refreshed but the typed letters have the blue heading formatting. In this case formatting is simply not removed. It has always worked that way for these two browsers.
