Hey,

The Survey block refers to 

@import url("https://surveyjs.azureedge.net/1.0.85/survey-creator.css");

in the CSS, but should probably be changed to 

https://unpkg.com/survey-creator@1.1.20/survey-creator.css

or similar since the above resource is no longer present.

The component is broken as it is right now.
