Trying to add new attributes to the LocalParticipant fails.

• User token has CanUpdateOwnMetadata set true.
• No error is seen in the browser console unless a call to access the attribute is made
• Setting participant Name or Metadata functions as expected

Calling a count of the participant attributes and new attribute JSMap argument using the following snippet produces the output at bottom of the post, which seems like something is wrong with the underlying object

Debug.Log($"Participant.attributes count before: {Participant.attributes.Count}");
JSMap<string, string> attributes = new JSMap<string, string>();
attributes.Add("MyAttribute", "myValue");
Debug.Log($"attributes count: {attributes.Count}");
yield return Participant.SetAttributes(attributes);
Debug.Log($"Participant.attributes count after: {Participant.attributes.Count}");

This is the output:

Participant.attributes count before: -2147483648
attributes count: 1
Participant.attributes count after: -2147483648
