ProgressBar draws progress incorrectly

Run the qtquickcontrols2 gallery example and navigate to the ProgressBar control.

Expected behavior: 

1) The indeterminate ProgressBar shows animation

2) The determinate ProgressBar shows progress up to the specified value, no animation

Actual:

1) The indeterminate ProgressBar doesn't draw any progress and doesn't show animation at all

2) The determinate ProgressBar shows animation outside of groove bounds
