Superuser Grants Permission to ADB even when set to Root to Apps Only

[optimumpr]

Builds fine, installs fine, works fine, except for still granting root via ADB even when set to granting root to apps only.

How to repeat: go to superuser settings, set to root to apps only, then enable adb, connect to PC, type adb shell, type su and root is granted for /data/data/

Also, when root is disabled within superuser, you can't return to any other settings. The only way to change it is through development settings.

This is on LP 5.1.1, custom rom...
