W2D3 Tutorial 3 video not showing #268
Description
The video cell automation that generates the video iframe of the video tutorial interacts with the Pluto notebook iFrame in some unintended way to produce 3 salient errors (potentially all with one source):
- the Pluto notebook is duplicated
- the video tutorial doesn't show
-there is some garbled jupyter json in a cell that is visible at the end of the notebook
