```sh
--parser typescript
```

**Input:**

```tsx
export /* c */ @dec class A {}
```

**Output:**

```sh
--parser typescript
```

**Input:**

```tsx
export // c
@dec class A {}
```

**Output:**

```tsx
export // c

@dec
class A {}
```

**Second Output:**

@dec
class A {}
```

### Expected output

```tsx
export /* c */
@dec
class A {}

export // c
@dec
class A {}
```

### Why?

Each format adds another blank line after the comment.

Also reproduces on `main` (88d8e96).
