unexpected behavior between subdivision repo getList() and getAll()

Hi there,

Working on a website (on CraftCMS) that handles states in the UK.

I've noticed that the subdivision repository `getAll(['GB'])` method returns an empty array where the `getList(['GB'])` return an array of 213 items.

I can't see anything fundamentally different between those 2 methods so wondering if this is a bug, or could you explain the difference between the two ?
