vscode auto-format (dangerously!) mangles code

Original code file `a.ts`:
```
class C {
    /**
     *
    */
    async x() {}
}
```

Press alt+shift+F and it becomes:

```
class C {
    /**
     *
     /
    async x() { }
} 
```

Press it again and it becomes:
```
class C {
/**
 *
 /
 sync x() { }
```
