i'm creating an API in Laravel 5.5 and this API supports receiving some files for profile pictures and such.

I want to limit this through a *form request* to accept only **JPG** and **PNG** images and i'm setting up my Form Request as follows:

```
    'picture'    => 'nullable|image|mimetypes:image/jpeg,image/png,image/jpg|max:2000' // 2000KB or around 2MB per picture

```

Then, on my PHPUnit/Codeception tests i'm sending a fake image using Laravel's own `fake` static method as follows

```
'picture' => UploadedFile::fake()->image("hello.svg")

```

If i DD the image file that is being sent when i run the test it correctly lists it's **MIMEType** as `image/svg+xml`, however, somehow this passes validation and comes out the other end and that should not be the case as my rule *should* limit only PNG or JPG files.

Does anyone else have this issue?
