Line comment after typedefs

**Describe the bug**<br/>
If there's a single-line comment there, it probably "belongs to" that line, but it's moved.

**Input file**
```haxe
typedef TypeParams = Array<String>; // no constraints
typedef Foo = Bar
```

**Broken output**
```haxe
typedef TypeParams = Array<String>;
// no constraints
typedef Foo = Bar
```
