How to reproduce :

• in the skin factory, in the Content tab, click on the "Introduction" button of the ribbon.
• Two properties have no options : italic and bold

Actual behavior :

• if your paragraph is already checked bold, you have to click on the bold menu to obtain a normal font.

Expected behavior :

• we should have a button which acts like an interuptor : when the paragraph is already in bold, it should have a check mark in front of the menu which disapears when the text is normal
