Reproduction link

Steps to reproduce
- Get code from Tree Transfer sample (https://www.antdv.com/components/transfer) or codesandbox.io link
- edit to remove "check-strictly" from a-tree template
- Select parent node '0-1' and see children nodes (0-1-0, 0-1-1) selected
- Tap ">" button
What is expected?
All selected nodes go to the right panel: 0-1, 0-1-0, 0-1-1
What is actually happening?
Only the explicitly selected nodes go to the right panel.
It could be parent node 0-1, if one manually click the child - that also go to the right.
Unfortunately I was not able to make codesandbox.io live, but setup is really basic.
