DataTable - Zebra Styling - Basic vs Expansion

[kgibb]

In a regular zebra styled DataTable, every even row has a grey background.

In a zebra styled DataTable with Expansion, every odd row has a grey background.

Is this intentional? The different child n selector rules in _data-table.scss and _data_table-expansion.scss suggests so.

I don't think the table with row expansion looks right especially since some child rows have the same background at their parent and some don't. The following screenshot is from expanding the first and second rows in https://react.carbondesignsystem.com/?path=/story/components-datatable-expansion--default&args=useZebraStyles:!true&globals=theme:g10:

@laurenmrice, is the appearance of zebra styled DataTables with expansion correct? I don't see any visual testing for them in Percy so I'm not sure.
