Putting custom annotation on Drone creates multiple instances

I have a test case like this

@RunWith(Arquillian.class)
@RunAsClient
public class SomeTestCase
{
    @Drone
    @Mobile
    @Custom
    private WebDriver mobile;

    // tests
}

where @Custom is just an annotation:

@Retention(RetentionPolicy.RUNTIME)
@Target({ ElementType.FIELD, ElementType.PARAMETER })
public @interface Custom {
}

it is not annotated with @Qualifier.

Realize that the same problem arise when using @OperateOnDeployment from Arquillian which is not annotated with @Qualifier neither.

I am getting this:

You see that InstrumentationPerformDecider.decidePerformingInstrumentation observes BeforeDroneInstantiated so when it is treated twice, you are going to instantiate two Drones which is another argument why Drone does it wrong.

When I declare Drone injection like that, it results into two instances of WebDrivers so that means it instruments Android package twice with two Selendroids so that mean I am getting NoUniqueWebDriverException when I want to start some activity because from now on you have "by accident" two webdrivers instrumenting the same deployment as a result of a bug where putting custom annotation on Drone instantiates it twice.
