As you @venkatbhoogarbh can see, the click changes here something. Is this a desired behavior ?

The lint checks look good now! I see the screenshot test caught the visual differences caused by the stacked-bar highlighting fix. Since forks don't have permission to modify the baseline snapshot files directly, let me know if you need any other changes from my side, or if this copy is good to go!

The lint is still failing.

This is just to verify the screenshot test mechanism.
