In JS, typedef tags are not bound on non-expression statements

```js /** @typedef {number} A */ var ok; /** @typedef {number} B */ ok = 1; // also ok /** @typedef {number} C not ok */ ; /** @typedef {number} D not ok */ if (ok) { } /** @type {[A, B, C, D]} */ var t = [1,2,3,4] ``` **Expected behavior:** All of A, B, C, and D are type aliases for number. **Actual behavior:** Cannot find name 'C' and 'D'.
