In using the control I've noticed that the developer console (web browser within Chrome) notes warning below. Are there any plans to migrate the control's HTTP interactions to the recommended patterns?

[Deprecation] Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check https://xhr.spec.whatwg.org/.

Hi Robert, 
  
Thank you for using Syncfusion products. 
  
As of now, we do not have immediate plans to migrate the HTTP requests of the PDF viewer as a separate thread. This feature may be available in any of our future releases. 
  
Please let us know if you need any further assistance. 
  
Regards, 
Sabari Anand
