Correct overbroad automatic capability grant of global settings objects
This exception is too broad and grants everyone all capabilities, not just "CAN_VIEW". In particular, it incorrectly grants "CAN_EDIT", so any user can edit global settings defaults.
Restrict this grant to "CAN_VIEW".
- As a non-administrator, tried to edit global settings.
- Before: could.
- After: could not.
