IoC binding changes object creation order

[Yoooi0]

I might not be fully understanding something but when I add: (did not test other bindings)

builder.Bind<T>().ToSelf().InSingletonScope();

the order in which the objects are created/injected changes.
Is this behavior expected?

Example:

   public class Root
    {
        [Inject] public FooA FooA { get; set; }
        [Inject] public FooB FooB { get; set; }

        public Root() => Debug.WriteLine("Root");
    }

    public class FooA
    {
        public FooA() => Debug.WriteLine("FooA");
    }

    public class FooB
    {
        [Inject] public Bar Bar { get; set; }

        public FooB() => Debug.WriteLine("FooB");
    }

    public class Bar
    {
        public Bar() => Debug.WriteLine("Bar");
    }

In bootstrapper I call:

_ = Container.Get<Root>();

Console output (expected):

Root
FooA
FooB
Bar

If now I add to the bootstrapper:

    protected override void ConfigureIoC(IStyletIoCBuilder builder)
    {
        builder.Bind<FooB>().ToSelf().InSingletonScope();
    }

The console output changes to: (not expected?):

FooB
Bar
Root
FooA

It looks like IoC first resolves/creates all bindings and then proceeds with the actual object creation.
