Selecting font doesn't work for the first time

[Wiktor Walc]

Confirmed in IE8, works fine in FF, didn't test other browsers. When selecting font family straight after the editor loads, IE ignores it, setting font family again works.

Steps to reproduce

• Use an IE8 browser
• Open replacebyclass.html sample
• Before you click anything, click the font drop down on the toolbar.
• Select any font and click.
• problem: the font you selected doesn’t stick, it goes back the gray default item “font”.

We fixed this issue in 4.0.2 iirc. Most likely with #9507.
