toggleAllRowsExpanded on deeply nested table

[stuthib]

Hello everyone. I have a need to expand and collapse all on a deeply nested table. The depth is more 2. I am fetching the data and setting subRows property on each row. It works okay when I manually click on each row. When using toggleAllRowsExpanded, it only renders until depth 1. I see the data is right, but it does not render the rest of the nested rows. Is this supported in the table? Thank you!
