Why ref and computedRef has different behavior while unwarpping?

[wiidede]

Playground

const msg = ref('Hello World!')
const listWithRef = [{msg}]

const refVal = ref()
refVal.value = listWithRef
  
const computedRefVal = computed(() => listWithRef)

I have two question:

1. The ref will unwarpping the inner ref, but the computedRef will not. It make me confused when I notice it.
2. According to the guide: Ref Unwrapping in Reactive Objects & Ref Unwrapping in Arrays and Collections, my first thinking about listWithRef = [{msg}] will not unwarrping, because the ref is in a array. But maybe the truth is : the ref is in a object，I don't need to care about the object is in a array?
