Some fields of dependency telemetry are missing when dependency is invoked asynchronously

[a-stankevich]

• List of NuGet packages and version that you are using:
  • Microsoft.ApplicationInsights.Web 2.21.0 and it's dependencies
• Runtime version (e.g. net461, net48, netcoreapp2.1, netcoreapp3.1, etc. You can find this information from the *.csproj file):
  • net48
• Hosting environment (e.g. Azure Web App, App Service on Linux, Windows, Ubuntu, etc.):
  • Azure Web App
  • Windows

Describe the bug

While processing request application can make calls to external dependencies, like HTTP or SQL servers. When such calls are done in a synchronous manner (e.g. using WebClient.DownloadData(), EF DbSet.ToList()) corresponding dependency telemetry includes Operation Id as well as Operation Name, User Id, Session Id from request. When such calls are done in asynchronous manner (e.g. using HttpClient.GetAsync(), EF DbSet.ToListAsync()) corresponding dependency telemetry includes only Operation Id, but not Operation Name, User Id, Session Id from request.

This happens at least for HTTP, SQL dependencies. Example screenshot of dependency telemetry for one request:
