Why sometime customize Option cause scroll break?

You can ref Select FAQ.

Why `loadData` not trigger when searching?

In earlier version, loadData will be triggered when searching. But we got feedback that it will block network when inputting. So we change it to not trigger loadData when searching. But you can still handle async logic by filterTreeNode:

<TreeSelect
  filterTreeNode={(input, treeNode) => {
    const match = YOUR_LOGIC_HERE;

    if (match && !treeNode.isLeaf && !treeNode.children) {
      // Do some loading logic
    }

    return match;
  }}
/>

Just turn off virtual scrolling, because the scrollWidth of the complete list cannot be accurately measured when virtual scrolling is turned on.
