Component used: Navigation Version used: 2.2.0-rc04

https://issuetracker.google.com/issues/123449431 added ProGuard rules to navigation-ui to ensure that the back button remains functional with minifyEnabled.

However, those rules were written in the Support Library time and jetifier would convert them to the appropriate AndroidX versions when using Navigation 1.X with an AndroidX project:

# setProgress is called via an ObjectAnimator in AbstractAppBarOnDestinationChangedListener
-keepclassmembers class android.support.v7.graphics.drawable.DrawerArrowDrawable {
    void setProgress(float);
}

Since Navigation moved to 2.X and is now part of AndroidX, Jetifier does not apply any transformations and navigation-ui's ProGuard rules need to be updated to reflect the appropriate AndroidX package name for DrawerArrowDrawable (androidx.appcompat.graphics.drawable.DrawerArrowDrawable).
