[jespirit]

The _state is overridden because the statement below does not actually create a temporary copy of the state.

1. Open a console
2. Move the handle to the middle (value of 5).
3. Hover over the rightmost tick once. Should display hover: 5
4. Repeat step 3 multiple times. Should display hover: 2

Note: Also try hovering over the leftmost tick.

console.log('hover:', mySlider.getValue());
