Vue Ts (2.7 -> 3.3+) Nested type Ref<T> removed

Vue version

[2.7.10 => 3.3.4]

Link to minimal reproduction

https://stackblitz.com/edit/vitejs-vite-3ivkqw?file=src%2FAlert.ts&terminal=dev

Steps to reproduce

If you have a nested type (like in Alert.ts of the Stackblitz link) using Ref it is purged out when using it.

IE: Ref<boolean> | boolean will become boolean

What is expected?

The Ref should be available within the parent type

IE: Ref<boolean> | boolean will stay Ref<boolean> | boolean

What is actually happening?

Ref<boolean> | boolean will become boolean
