DI IHttpContextAccessor.HttpContext is null after upgrade to 2.2.0

General

After upgrade aspnet core nuget packages from version 2.1.0 to 2.2.0 I've got issue IHttpContextAccessor.HttpContext unexpectedly became null during dependency injection.
I've investigated problem and found the cause of the problem was override HttpContext.TraceIdentifier in middleware. For 2.1.1 it was working well.

Details

Middleware:

public class DistinctTraceIdMiddleware
{
    private readonly RequestDelegate _next;
    public DistinctTraceIdMiddleware(RequestDelegate next)
    {
        _next = next;
    }
    public async Task Invoke(HttpContext context)
    {
        // !!! OVERRIDE cause of HttpContex = null !!!
        context.TraceIdentifier = Guid.NewGuid().ToString("N");
        await _next(context);
    }
}

Resolving dependency in Startup.cs

public IServiceProvider ConfigureServices(IServiceCollection services)
{
    ConfigureDefaultServices(services);
    services.AddOptions();

    services.AddTransient<ConfigurationResponse>(serviceProvider =>
    {
        var httpContextAccessor = serviceProvider.GetRequiredService<IHttpContextAccessor>();
        if (httpContextAccessor?.HttpContext == null)
        {
            // !!! it should not be null but it is
            throw new Exception("Why HttpContext is null?");
        }

        return new ConfigurationResponse();
    });

    return services.BuildServiceProvider();
}

@davidfowl / @Tratcher - ideas on this?

Dupe of #5144. It's a bug in 2.2 that's being fixed in a patch. See the other issue for details.

Is this a bug at 2.2.301 yet?
I have an integration test with WebApplicationFactory and it works fine with dotnet 2.2.101. And anothe machine with dotnet 2.2.301 this test fail with System.NullReferenceException at IHttpContextAccessor.HttpContext.

So then to confirm that, I update this first machine with dotnet 2.2.301 and then, my test with IHttpContextAccessor.HttpContext become fail too.

More stranger is because I have a global.json with 2.2.101 SDK reference.
My output was:

# dotnet --version
2.2.101

# dotnet --list-sdks
