My Setup:

• Visit http://localhost:3000/benwbrum/citsci-2021-workshop/fieldnotesmexic00pete/display/25076988
• Add a row of equals signs at the bottom and save
• Add "Title" at the top of the transcript and save

Observed behavior

• Select the version with the added equals signs and compare it with an earlier version: all looks fine (fig. 1)
• Now compare it with a later version: the "Title" text which was added in the later version looks like it was deleted (fig. 2)

We need to make another pass at this following these principles

• Text added in a later version always appears as green compared to text in an earlier version
• Text deleted in a later version always appears as red/strike-through compared to text in an earlier version
