Highlight field in Select Color dialog not showing correct color when we navigate Colors using keyboard

[Satya Minnekanti]

To reproduce the defect:

1. Open any CK Editor sample & insert a table.

2. Open Context menu and click on Cell -> Cell Properties option.

3. Cell Properties dialog opened.

4. Click on Choose button next to Background Color.

5. Select Color dialog opened.

6. Now navigate through the Colors list using keyboard and verify the Color shown in the Highlight field.

Issue: Highlight field always showing the last color that we navigated.

I have attached a screenshot of the error

Issue has been reproducible from CKEditor 3.3 (when moving with arrows was implemented)

My observation:

• Put the cursor in one of first cells on the left E.g. 6th row (color - #0000ff)
• Start moving to the right with arrow key
• Hightlighted color is one color behind.

Despite 1 color being late:

• After pressing arrow key 7 times you should reach #3300ff
• Color #3300ff is next to #00ffff so pressing left arrow should move the hightlight to #00ffff

Actual Result:
Highlight will be moved to the right first (probably because of this one late right arrow press)
So when you are on #3300ff and you start pressing left arrow the result is as follows: #3333ff (color on the right),#3300ff, #00ffff (color on the left.)
