`IconView` creates a new drawable and makes it mutate for scaling it during some animations. The `setDrawable` function there also performs more logic and invalidate the view. Thus, every time `setDrawable` is called in the `IconAppChipView`, even if the same drawable is provided, it will unnecessarily create a copy of the drawable, invalidate and redraw the whole view.
To prevent this inefficient behavior, a hash check has been introduced in `IconAppChipView`. This hash check skips the redundant logic if the same drawable is provided to `setDrawable`.
