Group header rows cannot be edited, and if using the selection feature, cannot be selected <INVALID>

Hi All,

This feature makes the selection confusing.
Because when user is selecting all at the top level they want to know which of the rows are selected with out having to expand all the rows.

I humbly request this feature to be enabled back please.
It causes lot of confusions.

I found out that my fix only worked for the complex grouping tutorial
