[Device Support / Bug]: Incorrect color selection / color jumping issue for [TS0505B_1_1]

What happened?

When changing the color using the color picker in Zigbee2MQTT, the lamp does not set to the selected color. As soon as I release the color picker wheel, the color suddenly jumps to a completely different color (e.g., pink or green). The color selection is unpredictable and unstable.

What did you expect to happen?

The lamp should stay on the exact color selected on the color wheel without jumping to other colors.

How to reproduce it (minimal and precise)

1. Go to the device control tab in Zigbee2MQTT.
2. Drag the color picker to any specific color.
3. Release the picker and observe the physical lamp color changing unexpectedly to a different tone (like pink or green).

Start by reproducing the color-picker behavior in the Zigbee2MQTT device control tab and review the debug log alongside the TS0505B_1_1 device definition. Compare the reported color, color_mode, color temperature, and XY values; done means the lamp remains at the color selected on the wheel.
