Challenge Creator Thumbnail

I expected the Challenge Thumbnail to behave the same way that regular thumbnails on the teacher dashboard do. However I am experiencing an issue where the background layer of the of the thumbnail does not appear.

This activity describes and illustrates the issue.

Hi @mxepstein. I was able to get a better thumbnail by

  1. Defining the bounds of the sketch and graph
  2. Defining the background and bounds for the challenge in the CL:
challengeBackground: layerStack(graphLayer(graphWithSketch.calculatorState), sketchLayer(sk.sketch))
challengeBounds: sk.bounds
