Unexpected Darkening of Shape Backgrounds on shape move

[PriyaYadav7733]

I've noticed a strange visual behavior while interacting with shapes like FibRetracement and GannFan on the chart.

Issue:
When I click on any of these shapes, and then dragging that shape their background color appears to darken unexpectedly. This effect isn’t consistent with the intended design or user experience, and it creates a distracting visual inconsistency — especially when working in themes or styles where precision in color representation matters.

Expected : Background opacity should not change while dragging
