In showcase -> Grouping: if applying a filter on the "Weight" column, the expansion of the rows does not appear to work properly.
The automated test is successful because it does not test row expansion combined with filtering.

Issue1: unable to expand a row for certain applied filters
1. Enter '4' in 'Weight' filtering input text -> two rows will be rendered.
2. Try to expand each row -> only first row can be expanded.
Removing followed by re-applying the filter will render the second row being expanded.

Issue2: first row duplication
1. Enter '1' for 'Weight' filtering text -> 15 rows rendered.
2. Try to expand first row (ID=4) -> this row will be expanded but it is rendered twice, each instance calculating different values for the Cost Per Pound.
3. Trying to expand a different row will still duplicate the first row, and the row fails to expand.
Removing the filter and then re-entering the filter removes the duplicated row.

Row expansion is functional on this demo if no filters are applied.
