There are some things we can do to check the quality of the data in CSSProperties.json5, especially in relation to Project Ribbon:


- Check that objects with the same api_class have matching data

- Check that API impls to verify that their method overrides match their json data. E.g. if the json object has direction_aware_options then the API class should have ResolveDirectionAwareProperty override.

- Check order of members in data objects.
