CKEditor 3.2.1. : FireFox font size not correct

This is how to reproduce this problem:

• blank your editor textarea
• select a font name and font size something like "Comic Sans MS" and size 20. This will help see the problem easier.
• Type "ABCD" from previous step (same line without typing anything else)
• change the "ABCD" word to "Tahoma" and move the cursor to the end of "ABCD"
• now type " EFGH" right after "ABCD"
• move the cursor between "ABCD" and "EFGH" and click the end key (from the keyboard).
• Type "IJKL"

*problem 1: The last word has the same font name as the other words but not the same font size. *problem 2: It has been reported that sometimes the font name is not the same in the last word. "IJKL" in this case.
