Laravel Eloquent ignores mutator in polymorphic relationship

I have a model Image and a model Metadata. Metadata can belong to Image, but it can also belong to other models, so I use a polymorphic relation:

Image.php:

public function metadata()
{
    return $this->morphMany('App\Metadata', 'content');
}

Metadata.php:

public function content()
{
    return $this->morphTo();
}

public function setAuthorAttribute($value)
{
    $this->attributes['author'] = strtoupper($value);
}

When I want to create an image with its metadata, which looks like this:

["author" => "Foo Bar"]

I use this code:

$image = Image::create($request);

$image->metadata()->create($this->mapMetadata($request));

This works well. But when I try to update an image with its metadata, with this code:

$image = Image::findOrFail($id);   

$image->update($request);

$image->metadata()->update($this->mapMetadata($request));

The data is updated, but my mutator is ignored. In other words, when creating, the author is turned to uppercase, but when updating, it's not.

EDIT: Migration for Metadata table:

$table->increments('id');   
$table->string('author')->nullable();
$table->unsignedInteger('content_id');
$table->string('content_type');

You may use undocumented morphOne relationship.

And $image->metadata->update(..) should work.
