Guidelines

• I have read the FAQ and it doesn't cover the issue.
• I have searched the issue tracker for open and closed issues that are similar to the feature request I want to file, without success.
• I'm on the latest version.
• I'm not using a test build (alpha/beta/release-candidate).
• This issue contains only one bug.

Describe the bug

• make backup of a system app (for example com.android.chrome) that has been subsequently updated. backup both the apk and the data
• uninstall updates to the system app
• restore both the apk and the data of the system app from backup

Expected Behavior

the both APK and data should restore properly, but instead the restore of the APK fails silently (installed app version is still the old version), but data restore succeeds
