Because of event bubbling. The child's click event bubbles up to the parent, triggering the parent's click handler. Fix: call e.stopPropagation() in the click handler to prevent bubbling.
Check if the folder has children before showing the expand icon and click handler: if (node.children && node.children.length > 0). Empty folders should not be clickable or show an expand icon.
