[FIXED]Vertical slider and negative values

[Seboss]

When using a negative value for minValue in a vertical slider, the slider resets to minValue when dragged.

Ext.onReady(function() {
    Ext.create('Ext.slider.Single', {
        //renderTo: "target",
        hideLabel: true,
        height: 200,
        vertical: true,
        increment: 1,
        minValue: -10,
        maxValue: 10,
        value: 1,
        listeners: {
            change: function(slider) {
                console.log(slider.getValue());
            }
        }
    }); 
});
