Any additional comments?

I think the reason for this bug is that defineProps has the wrong type when destructuring. When using reactivity transform, the variable deconstructed by defineProps should be of type ReactiveVariable<T> rather than T. Because of this reason, the type of $$() is wrong.

This is not a bug, try the following code:

const txArr = $ref(data)
$$(txArr)

Further explanation

Since the value you pass in is not a "reactive variable", "$$" function will think that you are trying to deconstruct array. e.g. const [fooRef, barRef] = $$([reactiveFoo, reactiveBar])

Thank you! It's useful!
