Expand row functionality has a inconsistent behavior for different user interactions.
When user clicks on plus button to expand row of the grid. It shows summary of the row as the last row in expanded rows.
Whereas when expand all functionality is used, provided as expandAll function. This last summary row is not seen.
You can observe the problem mentioned in attached images. It can be seen that “Cash and cash equivalents” summary row is not there for exapndAll image.
Unfortunately the issuer cannot be reconstructed locally locally.
