Android 8 pop-up window BUG when requesting permission

Pop-up BUG

When the application uses requestPermissions to apply for permissions, the system will pop up a selection window to allow or deny.
In this window, there is a "Don't ask again" selection box, "Deny" and "Allow" buttons.
Encountered a bug, click "Don't ask again", the "Allow" button will be grayed out and disabled.

Locate the source code in the packages/apps/PackageInstaller file.
GrantPermissionsActivity is a pop-up window for permission assignment. GrantPermissionsDefaultViewHandler is used to control the ui view of GrantPermissionsActivity. Button click events are handled through the GrantPermissionsViewHandler.ResultListener interface, which is implemented by GrantPermissionsActivity

public class GrantPermissionsActivity extends OverlayTouchActivity
        implements GrantPermissionsViewHandler.ResultListener {
    
    
            mViewHandler = new com.android.packageinstaller.permission.ui.handheld
                    .GrantPermissionsViewHandlerImpl(this, getCallingPackage())
                    .setResultListener(this);
}
