Expected behavior 🤔

1. Select "20th Century Fox (3)" which is the parent of "James Cameron (2)" which is the parent of "Avatar" and "Titanic"
2. "20th Century Fox (3)" is selected
3. "James Cameron (2)" is selected as it is a child of Step 2
4. "Avatar" and "Titanic" are selected as it is a child of Step 3
   

Context 🔦

Trying to combine grouping and checkboxSelection. The UX for grouping is great, since the parent of a group is likely to show summarized content of it's children, it is expected that when clicking the parent that the selection follows into the children rows
