styles combo behavior question.

Hi,

Selecting the same font name or font size seem to toggle between the default font and the selected font. Is this the behavior of ckeditor? Is there any configuration to change this behavior?

For example, if I select a text and apply font size "16", the text is displayed with font size 16. If I select the same text again and select size "16", the text changes to the default font. Is there a way to make it not toggle?

Thanks
Anand
