ArgumentException when using several converters with same TFrom type

[Hellfim]

Suppose you have following files:

MyView.uxml

<ui:UXML xmlns:ui="UnityEngine.UIElements" xmlns:uie="UnityEditor.UIElements" xsi="http://www.w3.org/2001/XMLSchema-instance" engine="UnityEngine.UIElements" editor="UnityEditor.UIElements" noNamespaceSchemaLocation="../../../../UIElementsSchema/UIElements.xsd" editor-extension-mode="False">
    <ui:VisualElement style="flex-grow: 1; align-items: center; justify-content: center;">
        <MyCustomControl binding-bool-path="ResultProperty, ResultToBooleanConverter" text="Label" style="font-size: 130px;" />
        <MyCustomControl binding-bool-path="ResultProperty, InvertedResultToBooleanConverter" text="Label Inv" style="font-size: 130px;" />
    </ui:VisualElement>
</ui:UXML>

Result.cs

    public enum Result
    {
        Defeat,
        Victory,
    }

ResultToBooleanConverter.cs

    public class ResultToBooleanConverter : PropertyValueConverter<Result, Boolean>
    {
        [MethodImpl(MethodImplOptions.AggressiveInlining)]
        public override Boolean Convert(Result value)
        {
            return value == Result.Victory;
        }

        [MethodImpl(MethodImplOptions.AggressiveInlining)]
        public override Result ConvertBack(Boolean value)
        {
            return value ? Result.Victory : Result.Defeat;
        }
    }

InvertedResultToBooleanConverter.cs

    public class InvertedResultToBooleanConverter : PropertyValueConverter<Result, Boolean>
    {
        [MethodImpl(MethodImplOptions.AggressiveInlining)]
        public override Boolean Convert(Result value)
        {
            return value != Result.Victory;
        }

        [MethodImpl(MethodImplOptions.AggressiveInlining)]
        public override Result ConvertBack(Boolean value)
        {
            return value ? Result.Defeat : Result.Victory;
        }
    }

MyView.cs

    public class MyView : DocumentView<MyViewModel>
    {
        protected override IValueConverter[] GetValueConverters()
        {
            return new IValueConverter[] { new ResultToBooleanConverter(), new InvertedResultToBooleanConverter() };
        }
    }

MyViewModel.cs

    public class MyViewModel : IBindingContext
    {
        public IProperty<Result> ResultProperty { get; }

        public TestCaseViewModel()
        {
            ResultProperty = new Property<Result>(Result.Victory);
        }
    }

MyCustomControl.cs

    [UxmlElement]
    public partial class MyCustomControl : VisualElement, IBindableElement
    {
        [UxmlAttribute("binding-bool-path")]
        private String _bindingBoolPath { get; set; }
        private PropertyBindingData _isDisplayPathBindingData;

        private IReadOnlyProperty<Boolean> _boolProperty;

        public void SetBindingContext(IBindingContext context, IObjectProvider objectProvider)
        {
            if (String.IsNullOrWhiteSpace(_bindingBoolPath))
            {
                return;
            }

            _isDisplayPathBindingData ??= _bindingBoolPath.ToPropertyBindingData();

            _boolProperty = objectProvider.RentProperty<Boolean>(context, _isDisplayPathBindingData);
            _boolProperty.ValueChanged += OnBoolPropertyValueChanged;

            UpdateControlValue(_boolProperty.Value);
        }

        public void ResetBindingContext(IObjectProvider objectProvider)
        {
            UpdateControlValue(false);
        }

        [MethodImpl(MethodImplOptions.AggressiveInlining)]
        protected virtual void UpdateControlValue(Boolean newValue)
        {
            Debug.Log($"Value changed to: {newValue}");
        }

        private void OnBoolPropertyValueChanged(Object sender, Boolean flag)
        {
            UpdateControlValue(flag);
        }
    }

This configuration produces following exception
