Missing information on Context in Razor

[dawidkowal]

DefaultHttpContext holds empty HttpContext.Request information.
could you add it ?

services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();

IHttpContextAccessor _httpContextAccessor;

   public class RazorViewToStringRenderer : IRazorViewToStringRenderer
    {
        private readonly IOptions<MvcViewOptions> _options;
        private readonly ITempDataProvider _tempDataProvider;
        private readonly IServiceProvider _serviceProvider;
        private readonly IHttpContextAccessor _httpContextAccessor;

        public RazorViewToStringRenderer(
            IOptions<MvcViewOptions> options,
            ITempDataProvider tempDataProvider,
            IHttpContextAccessor httpContextAccessor)
        {
            _options = options;
            _tempDataProvider = tempDataProvider;
            _httpContextAccessor = httpContextAccessor;
        }

        private ActionContext GetActionContext()
        {
            return new ActionContext(_httpContextAccessor.HttpContext, new RouteData(), new ActionDescriptor());
        }
    }

Razor context request parameters , schema

@{ var a = Context; }
