DateOnly string does not deserialize to DateOnly Object when target is object

[niklasweimann]

DateOnly string does not deserialize to DateOnly Object when target is object. But DateTime strings are deserialized to DateTime objects when the string is in the correct format for a DateTime object (see JsonSerializerSettings.DefaultDateFormatString).

Source/destination types

object[]

Source/destination JSON

["2023-03-13T10:12:47.1830163+00:00",123,"9999-12-31"]

Expected behavior

Deserialize as DateOnly Object

Actual behavior

Deserializes as string

Steps to reproduce

var list = new object[] { DateTime.Now, 123, DateOnly.MaxValue };
var json = JsonConvert.SerializeObject(list);
var listDeserializeObject = JsonConvert.DeserializeObject<object[]>(json);
Assert.AreEqual(list[0], listDeserializeObject[0]); // Working: Type == DateTime
Assert.AreEqual(list[1], listDeserializeObject[1]); // Working: Type == int
Assert.AreEqual(list[2], listDeserializeObject[2]); // Not Working: Type == string, but should be DateOnly
