Summary:
Previously we would only consider a node hit if the nouse pos was inside every parents. There are a few reason why this isnt ideal:
1. Fragments are return 0 bounds
2. Many hierachys (particually in litho ) have nonsensical strucutres where your parent may have hieght 0, or children overflow parents bounds. Therefore it was impossible to select many nodes but unclear why
