Research direction
The issue is that alpha channel does not update when changing color via property or palette. Start by examining the color change handler in the component, likely in the Sketch or Chrome preset. Look at how the alpha value is extracted from the color object and passed to the state update. Check the `onChange` callback to ensure alpha is included. The bug may be in the Alpha slider component or the parent component's color transformation logic. Review the 6 comments in the issue for any diagnostic hints or proposed fixes.
