Conditional formatting pop-up window displays incorrect color when color selection pop-up closed by outside click

The conditional formatting pop-up window in some cases displays colors that do not get applied. To reproduce:

1. Navigate to a Flexmonster table, for example the one on this demo page: https://www.flexmonster.com/demos/js/pivot-table/
2. Open the conditional formatting pop-up window.
3. Click on the A to open a color selection pop-up window.
4. Choose a different color from the one currently selected.
5. Close the color pop-up window by clicking on the conditional formatting pop-up window. In particular, do not click on either of the "Cancel" or "Apply" buttons.
6. Observe that the A is the color selected in the color pop-up window.
7. Click "Apply" in the conditional formatting pop-up window.

Result: The color is not applied.

Expected result: Either of the following:

• The color is applied. This would be as if the user clicked "Apply" in the color selection pop-up window.
• The A in the conditional formatting pop-up window shows the same color as when the pop-up window opened. This would be as if the user clicked "Cancel" in the color selection pop-up window.
