Implicit cast for indexer isn't working

[viceice]

It seem ClearScript doesn't try to implicit cast the indexer key to the target type, like it's doing for method calls.

[DefaultScriptUsage(ScriptAccess.ReadOnly)]
[ImmutableValue]
public struct JsUuid
{
    internal readonly Guid _value;
    public static readonly JsUuid Empty = new(Guid.Empty);
    public JsUuid() => _value = Guid.NewGuid();
    public JsUuid(Guid value) => _value = value;
    public JsUuid(JsUuid value) => _value = value;
    public JsUuid(string value) => _value = new Guid(value);

    public static implicit operator Guid(JsUuid value) => value._value;

    public static implicit operator JsUuid(Guid value) => new(value);

    [ScriptMember("parse")]
    public static object Parse(object value)
    {
        return value switch
        {
            JsUuid res => res,
            Guid res => new JsUuid(res),
            string js when Guid.TryParse(js, out var res) => new JsUuid(res),
            _ => null
        };
    }
}

public sealed class UuidTestObject
{
    internal const string GS = "00bfea71-e717-4e80-aa17-d0c71b360101";
    internal static readonly Guid G = Guid.Parse(GS);

    [ScriptMember("item")]
    public object this[Guid g] => g == G ? true : null;

    [ScriptMember("item")]
    public object this[string g] => g == GS ? true : null;

    [ScriptMember("func")]
    public object Func(Guid g) => g == G ? true : null;
    [ScriptMember("func")]
    public object Func(string g) => g == GS ? true : null;
}


Engine.AddHostType("Uuid", typeof(JsUuid));
Engine.AddHostObject("func", new Func<Guid, bool>((g) => g == G));
Engine.AddHostObject("obj", new UuidTestObject());

// works
Expect(Engine.Evaluate("func(Uuid.Empty)")).To.Equal(false);
Expect(Engine.Evaluate($"func(Uuid.parse('{GS}'))")).To.Equal(true);
Expect(Engine.Evaluate("obj.func(Uuid.Empty)")).To.Equal(null);
Expect(Engine.Evaluate($"obj.func(Uuid.parse('{GS}'))")).To.Equal(true);
Expect(Engine.Evaluate("obj.item('')")).To.Equal(null);
Expect(Engine.Evaluate($"obj.item('{GS}')")).To.Equal(true);

// fails
Expect(Engine.Evaluate($"obj.item(Uuid.parse('{GS}'))")).To.Equal(null);
Expect(Engine.Evaluate("obj.item(Uuid.Empty)")).To.Equal(null);
