Yii2 Image validator throws an error if it is not image file

I have a simple validator for image file input which looks like this:

public function rules()
{
    return [
        ['thumbnail', 'image', 'minWidth' => 800],
    ];
}

But if I try to send a txt file, it does not show an error message, but the ImageValidator throws me an error:

PHP Notice – yii\base\ErrorException
getimagesize(): Read error!

Why does this happen? Why does it not stop on the image rule and why does it call getimagesize if it is not an image file? How can I suppress it?

After few times I have this workaround:

['thumbnail', 'image', 'minWidth' => 800, 'when' => function($model) {
    $check = @getimagesize($model->thumbnail->tempName);
    if( !$check ) $model->addError('thumbnail', 'File is not an image.');
    if( !$check['mime'] || !in_array($check['mime'], ['image/jpg', 'image/jpeg']) ) $model->addError('thumbnail', 'File is not jpeg.');
    return $check ? true : false;
}],

BUT the correct form is

['thumbnail', 'image',
    'extensions' => ['png', 'jpg', 'gif'],
    'mimeTypes' => ['image/*'],
    'minWidth' => 800],
