`Slider` in Droid only allows negative values if the Minimum property is set to a negative value

[jasonxz]

Current behavior

When setting the Minimum property of a Slider to a negative number, the Maximum is automatically set to 0.

Expected behavior

Setting the Minimum should not affect the Maximum as long as the Minimum is less than or equal to the set Maximum.

How to reproduce it (as minimally and precisely as possible)

The following XAML will produce a Slider with Minimum of -500 and a Maximum of 0 (even though Maximum is explicitly set to 500). <Slider Margin="4,0" Maximum="500" Minimum="-500"/> Carousel.zip

Workaround

If you set Minimum before Maximum, this works correctly: <Slider Margin="4,0" Minimum="-500" Maximum="500"/>

This seems to be working correctly now
