Color Picker does not change color on "OK" after having hit "Cancel"

[jgallred]

One of our program testers has discovered this bug.

When I try to change the font color or highlighting of text in a CKEditor text box, it doesn't actually change the color when I do the following:

1. Select the text
2. Click the "Text Color" or "Background Color" box
3. Click the "More Colors" option
4. Select a new color (by clicking on it once)
5. Click "Cancel"
6. Click "Cancel" on the popup box that asks if I really want to close without saving my changes (Then I am returned to the "Select color" window, with my new color choice still selected)
7. Click "OK"

Now my font/highlighting color should be changed to my new color, but it is not.
