Description
Players that do not have backpack.size permission are given a backpack anyways. It seems to give them a backpack upon having the perm backpack.use without the backpack.size permission being given.

Steps to reproduce
On my server for some reason I put the backpack.use perm for the default group. Not sure why other than basic perms to use a plugin are often given to the default group and perms regarding specific use are given in the appropriate rank group.

Players with only perm to use backpack are allowed to access a 1 row backpack despite not have the perm backpack.size.1
Expected behavior

I would not have expected players to get backpack with only the one perm. I would have expected such behavior to be documented.
Other information (e.g. detailed explanation, related issues, suggestions how to fix, links for us to have context, screenshots, etc.)

Yes, if a player has the backpack.use permission, the player will always get a backpack (with at least a size of 1).
This is to make the check if the player can use the backpack faster.
That behavior should be documented on dev.bukkit and spigot. But was indeed missing in the wiki (I have added it there)
