Bug? Spinner - wrap around

[kimstudio]

The B4J (ver 9.30) view Spinner with wrap around enabled, if the min value is a negative value like -5, the wrap around is not functioning correctly as I thought, either for up or down buttons.
spin up: 4 5 6 0 1 2 3
spin down: -4 -5 1 0 -1 -2

This is the behavior of the JavaFX control.

You can use B4XPlusMinus from XUI Views instead.
