SUMMARY
When the Advanced color selector is set to the triangle type, the triangle does not respond to neither touch nor the S Pen. The color blip is not moved to the selected point on the shape and foreground color is unchanged. The ring and the shade selector both work. 

When the foreground color is changed (from the working parts of the selector, from the color picker, or from other selectors), the blip updates correctly.

Other shape types work correctly.


STEPS TO REPRODUCE
1. Set the advanced color selector shape to triangle
2. Click the triangle to change foreground color


OBSERVED RESULT
The blip does not update, foreground color does not change.


EXPECTED RESULT
The blip moves to the selected position and foreground color is changed.
