navigationview back button does not hide if animation is not present (2.0.1 RC)

[anand.arvind]

If animations are not defined in naviation/Bar.js, function doChangeView

/**
* @private
*/
doChangeView: function(view, hasPrevious, reverse) {
var me = this,
leftBox = me.leftBox,
leftBoxElement = leftBox.element,
titleComponent = me.titleComponent,
titleElement = titleComponent.element,
backButton = me.getBackButton(),
titleText = me.getTitleText(),
backButtonText = me.getBackButtonText(),
animation = view.getLayout().getAnimation(),
animated = animation && animation.isAnimation && view.isPainted(),
properties, leftGhost, titleGhost, leftProps, titleProps;


if (animated) {
leftGhost = me.createProxy(leftBox.element);
leftBoxElement.setStyle('opacity', '0');
backButton.setText(backButtonText);
backButton[hasPrevious ? 'show' : 'hide']();

the bottom has the code

if (hasPrevious) {
backButton.setText(backButtonText);
backButton.show();
}

but also needs the code as follows

if (hasPrevious) {
backButton.setText(backButtonText);
backButton.show();
}
else
{
backButton.hide();
}

to hide the back button. Current examples have view.getLayout().getAnimation() defined so do not run into this, once this is null this case is triggered and when coming back to the first element in the stack the back button is still visible.

The workaround is to add an animation, but had removed it as I found that this made the Android native app less responsive and ideally want to remove the animation to make the transitions as fast as they can be. I can work around this by fixing the code and moving along, but good to get it fixed in the next dot release.
