P: The confirmation for the White Balance eye dropper can’t always be reached

When using the eye dropper tool to try selecting a colour value near the top or right edge of the screen, the tick button becomes unreachable. Would be super handy if the tick could rotate around the circle, or auto-change which 'corner' of the circle it sits on when approaching the edges of the screen (although as far as I can tell it only affects the upper and right edges - examples

attached)
