getValidData() returns new elements when using dot notation

[henninghorn]

I've noticed that the getValidData() returns new elements when using the dot-notation.

This is a snippet of my data

$data['logoImagePaths'] = [
    '1x' => 'http://example.com/1x.png',
    '2x' => 'http://example.com/2x.png',
];

Part of my rules:

'logoImagePaths'    => 'required|array',
'logoImagePaths.1x' => 'required|url',
'logoImagePaths.2x' => 'required|url',

And this is that getValidData returns:

print_r($validation->getValidData());

[logoImagePaths] => Array
(
    [1x] => http://example.com/1x.png
    [2x] => http://example.com/2x.png
 )

[logoImagePaths.1x] => http://example.com/1x.png
[logoImagePaths.2x] => http://example.com/2x.png

Is this expected? Or is it a bug?

No, it shouldn't return logoImagePaths.1x and logoImagePaths.2x. I think I'm missing something in setValidData and setInvalidData in Validation class. I will check it later after my vacation. PR are welcome.
