Slider.js trying to update none active handle at handleIdx of 0 not possible

[ccote]

hello,

My slider has 2 handles (handle1, handle2). While sliding handle2, I was trying to update the value of handle1 using the setValue(value, 0) was not possible. The main reason setValue method perform following check (handleIdx = handleIdx || this.activeHandleIdx || 0) to determine handleIdx. Since handle2 is active handle, telling setValue to update value handle1 at handleIdx=0 the check always return handleIdx=1.
