Description of the problem including expected versus actual behavior:

Nested ordering seems to ignore the filter when ordering the results.

Our indexed objects look something like this;

{
        "Name": "Item1",
	"SomeNestedData"{
		"SomeInnerNestedData": [
			{
				"fieldToFilterOn": 1234,
				"fieldToOrderOn": 2
			}
		]
	}
},
{
        "Name": "Item2",
	"SomeNestedData"{
		"SomeInnerNestedData": [
			{
				"fieldToFilterOn": 1234,
				"fieldToOrderOn": 1
			},
                        {
				"fieldToFilterOn": 5678,
				"fieldToOrderOn": 3
			}
		]
	}
}

Our sort descriptor looks something like this:

private static SortDescriptor<SearchItem> SortByNestedFieldValue(this SortDescriptor<SearchItem> descriptor, int filterValueToMatch)
    => descriptor
        .Field(f => f
            .Field(field => field.SomeNestedData.SomeInnerNestedData.Suffix("fieldToOrderOn"))
            .Descending()
            .Nested(n => n
                .Path(p => p.SomeNestedData)
                .Nested(n1 => n1
                    .Path(a => a.SomeNestedData.SomeInnerNestedData)
                    .Filter(filter => filter
                        .Term(f2 => f2
                            .Field(x => x.SomeNestedData.SomeInnerNestedData
                                .Suffix("fieldToFilterOn"))
                            .Value(filterValueToMatch))
                    )
                )
            )
        );

Our goal is to order everything based on the fieldToOrderOn but only if the filterValueToMatch matches our inputted value, every other fieldToOrderOn value should be ignored.

Expected Result

Given filterValueToMatch 1234 with descending ordering we expect:

1. Item1 (orderValue 2 for 1234)
2. Item2 (orderValue 1 for 1234)

Actual result:

1. Item2 (orderValue 1 for 1234, but with orderValue 3 for 4567)
2. Item1 (orderValue 2 for 1234)

Any help would be appreciated :)
