"Depends on permission ID" doesn't seem to actually do anything

[XFFA.IR Bot]

I have a "viewX" and "addX" permission in an add-on, the "addX" permission has "viewX" as the "Depends on permission ID". Both permissions are in the same group, however, I am able to set the "addX" permission directly to a user, user group, or through the moderator permission interface without assigning the "viewX" permission first. Additionally, the permission still returns true even without the dependent permission having a value set
