Routing-Controllers + class-validator bug?

When using the automatic validation from routing-controllers for some reason the email "patch@patch" is valid when we are using these validators and the "patch" validator group

@IsEmail({
        allow_display_name: false,
        allow_utf8_local_part: true,
        require_tld: true
    }, {
        groups: ["post", "patch", "login"]
    })
    @IsOptional({
        groups: ["patch"]
    })
    public email;

Doing it the manual way like so works however

let user = new UserValidation();
user.email = "patch@patch";
validate(user, {groups: ["patch"]}).then(console.log);
