treeSelect don't have expand interface and can't control select expand and select

What problem does this feature solve?

Custom treeNode select (as well as expand). Think about we don’t want to select parent node, but click to toggle show it’s children.

What does the proposed API look like?

const expandNode = (selectedKeys, e:{selected: bool, selectedNodes, node, event}) => {
  // some code to control tree expand
 // custom select expand, return false to prevent select hide
    return false
}
<TreeNode  onSelect={expandNode}>{xxx}</TreeNode>

Since expandedKeys & selectedKeys can control now. It makes happened: https://codesandbox.io/s/9zv8y9ow4y

@Miced , you can adjust the logic for sample above : )

This kindof works on TreeSelect, except that the dropdown closes upon select. If only there was a way to prevent this then it would work. Any advice?
