When Resolve is called multiple times, the parent collection is bound to the child container.

Hi 😄
I'm reporting what may be a glitch.

varsion: 1.10.0

Example

        [Test]
        public void ResolveCollectionFromParentByContinuous()
        {
            var builder = new ContainerBuilder();
            builder.Register<I1, MultipleInterfaceServiceA>(Lifetime.Singleton);
            builder.Register<I1, MultipleInterfaceServiceB>(Lifetime.Singleton);
            var parentContainer = builder.Build();

            var childContainer = parentContainer.CreateScope(childBuilder =>
            {
                childBuilder.Register<I1, MultipleInterfaceServiceC>(Lifetime.Singleton);
                childBuilder.Register<I1, MultipleInterfaceServiceD>(Lifetime.Singleton);
            });
            
            var scopedService = childContainer.Resolve<IReadOnlyList<I1>>();
            var moreScopedService = childContainer.Resolve<IReadOnlyList<I1>>();
            Assert.That(moreScopedService.Count(), Is.EqualTo(4));
        }

result

VContainer.VContainerException : Conflict implementation type : Registration MultipleInterfaceServiceA ContractTypes=[VContainer.Tests.I1] Singleton VContainer.Internal.InstanceProvider

If you check the contents of CollectionRegistration when you call Resolve for the second time, you will see that even the objects of the parent container are registered

registration = {Registration} Registration I1[] ContractTypes=[System.Collections.Generic.IEnumerable`1[VContainer.Tests.I1], System.Collections.Generic.IReadOnlyList`1[VContainer.Tests.I1]] Transient CollectionRegistration VContainer.Tests.I1[] ContractTypes=[System.Collections.Gener…
 ImplementationType = {RuntimeType} VContainer.Tests.I1[]
 InterfaceTypes = {List<Type>} Count = 2
 Lifetime = {Lifetime} Transient
 Provider = {CollectionInstanceProvider} CollectionRegistration VContainer.Tests.I1[] ContractTypes=[System.Collections.Generic.IEnumerable`1[VContainer.Tests.I1], System.Collections.Generic.IReadOnlyList`1[VContainer.Tests.I1]] Transient
   [0] = {Registration} Registration MultipleInterfaceServiceC ContractTypes=[VContainer.Tests.I1] Singleton VContainer.Internal.InstanceProvider
   [1] = {Registration} Registration MultipleInterfaceServiceD ContractTypes=[VContainer.Tests.I1] Singleton VContainer.Internal.InstanceProvider
   [2] = {Registration} Registration MultipleInterfaceServiceA ContractTypes=[VContainer.Tests.I1] Singleton VContainer.Internal.InstanceProvider
   [3] = {Registration} Registration MultipleInterfaceServiceB ContractTypes=[VContainer.Tests.I1] Singleton VContainer.Internal.InstanceProvider

Is it likely that calling Merge will keep it from being added?
