Setting the BackupWebStorage preference seems to have no effect.
1. Set BackupWebStorage in config.xml to local or none.
2. Build, install, and launch app.
3. On iOS device, open Settings -> iCloud -> Storage -> Manage Storage -> my_device_name -> Show All Apps
Expected: app should not appear since no data should be in storage.
Observed: app appears in iCloud storage regardless of BackupWebStorage setting.
