Enabling logging enrichment effects the logged message

[jamiewinder]

Description

Using EnableEnrichment on ILoggingBuilder causes the Message of the log events to be some type name.

Reproduction Steps

Example:

using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Diagnostics.Enrichment;
using Microsoft.Extensions.Logging;
using System.Text.Json;

var services = new ServiceCollection();

services.AddLogging(x => x
    .EnableEnrichment()
    .AddJsonConsole(y =>
    {
        y.JsonWriterOptions = new JsonWriterOptions()
        {
            Indented = true
        };
    }));

var serviceProvider = services.BuildServiceProvider();

var logger = serviceProvider.GetRequiredService<ILogger<object>>();

logger.LogInformation("this is a test");

This outputs

{
  "EventId": 0,
  "LogLevel": "Information",
  "Category": "object",
  "Message": "this is a test",
  "State": {
    "Message": "Microsoft.Extensions.Logging.ExtendedLogger\u002BLegacyTagJoiner",
    "{OriginalFormat}": "this is a test"
  }
}

If you disable / comment out the EnableEnrichment line:

{
  "EventId": 0,
  "LogLevel": "Information",
  "Category": "object",
  "Message": "this is a test",
  "State": {
    "Message": "this is a test",
    "{OriginalFormat}": "this is a test"
  }
}

Note the State.Message property value.

Expected behavior

The State.Message property should be unaffected.

Actual behavior

The State.Message property is the string "Microsoft.Extensions.Logging.ExtendedLogger\u002BLegacyTagJoiner"
