Hi Mem,

It seems like our tests broke from a recent change in the html docs. I didn't
know this, but apparently the docs get converted to json, but the step is still
manual :-(

Thanks Emily for helping me figure out how to fix it =)

This results in a diff in the generated dart files stored in the repository
(output of go.sh). I have uploaded a CL

to fix this.
