Fractal::collection return wrong data

[tranghaviet]

when I use fractal()->collection($collection, new MyTransformer()) for 3 different collections it return turn data as expected

{
    "views": 9,
    "story_id": 2,
}
{
    "views": 106,
    "story_id": 2,
}
{
    "views": 111,
    "story_id": 2,
}

But when I use \Spatie\Fractal\Facades\Fractal::collection($collection, new MyTransformer()) it all return same data (the last one I pass)

{
    "views": 111,
    "story_id": 2,
}
