Steps to reproduce

1. Create ref with Map that use generic

const reactiveMap = ref(new Map<number, T>());

2. Try to assign value from crated map in other place that expect this generic:

const test: T = reactiveMap.value.get(1)

You can check typescript error on line 14 in App.vue file in reproduction link.

What is expected?

Code works without any typescript errors.

What is actually happening?

Got error:

 Argument of type 'UnwrapRefSimple<T>[]' is not assignable to parameter of type 'T[]'.
  Type 'UnwrapRefSimple<T>' is not assignable to type 'T'.
    'T' could be instantiated with an arbitrary type which could be unrelated to 'UnwrapRefSimple<T>'
