Inspecting the JavaScript source for this package found some properties that are not in the .d.ts files.
The check for missing properties isn't always right, so take this list as advice, not a requirement.

plotly.js (unpkg)

was missing the following properties:

1. version
2. Fx
3. Snapshot
4. PlotSchema
