### 💻 Code

```ts
function f(x:[boolean, ...V, ...U], ...args:V) {
return x;
}

const a = f([true, 2, "b", true], 1, "a" ); //Error, expected 2 arguments, but got 3
```

### 🙁 Actual behavior

Compiler sees error

### 🙂 Expected behavior

No error, because as https://github.com/microsoft/TypeScript/pull/39094 states

> If the middle part of T is exactly two variadic elements ...A and ...B, and an implied arity exists for A, infer from a tuple consisting of the initial middle part of S to A and from a tuple consisting of the remaining middle part of S to B, where the length of the initial middle part corresponds to the implied arity for A.

As I understand the middle part of **S** is `2, "b", true` and in the middle part of **T** we have **...V**, **...U** then `2, "b"` is **...V** and `true` is **...U**.
