Action<ILogger, Dictionary<string, string>, Exception> _contextAction = LoggerMessage.Define<Dictionary<string, string>>(
            LogLevel.Information,
            new EventId(),
            "context = {Context}");

var logger = loggerFactory.CreateLogger("Default");
logger.LogInformation("context = {Context}", context);
_contextAction(logger, context, null!);

I was expecting this to be equivalent but seems the state is not serialized in the same way.

{
  "EventId": 0,
  "LogLevel": "Information",
  "Category": "Default",
  "Message": "context = [User, Jose]",
  "State": {
    "Message": "context = [User, Jose]",
    "Context": "[User, Jose]",
    "{OriginalFormat}": "context = {Context}"
  },
  "Scopes": []
}
{
  "EventId": 0,
  "LogLevel": "Information",
  "Category": "Default",
  "Message": "context = [User, Jose]",
  "State": {
    "Message": "context = [User, Jose]",
    "Context": "System.Collections.Generic.Dictionary\u00602[System.String,System.String]",
    "{OriginalFormat}": "context = {Context}"
  },
  "Scopes": []
}

Any idea why the first version State contains the serialized dictionary, and the second just the dictionary class name?
