Color wheel not updated when the mouse jumps outside the triangle

[LucaDC]

If I quickly drag the color point in the color wheel in the Fill and Stroke dialog outside the triangle (I usually do this to change the color to full black or full red or full whatever), the white circle goes in the correct place but the object gets another color.
Let's say we want to change a red border to black: you pick the circle in the red corner and abruptly drag it toward the black corner: the dot sticks to the vertex but the object gets a dark red color. If you deselect and reselect the object (or close and reopen the Fill and Stroke dialog), the white circle goes in the displayed color (dark red).

I suppose that the problem lies in the mouse coordinates jumping too much with fast movements: when the mouse cursor jumps outside the triangle, the white circle is correctly updated but the object color is not, so it retains the one corresponding to the last mouse coordinates seen inside the triangle.
To better reproduce the problem change the color of many objects at the same time, so the refresh rate is lower.
