Problem RectAreaLightHelper DragControls event - dragstart

Hey. Noticed one feature of RectAreaLightHelper or it’s a bug!

Using DragControls, I use the mouse to select the helper (drag.addEventListener (‘dragstart’).
Ok, it selected, but I can choose without clicking directly on the helper itself !! It is enough to click on the area around the helper and the helper will selected !! How?

let transform = new TransformControls(, renderer.domElement); 
let drag = new DragControls(objects,, renderer.domElement );

drag.addEventListener('dragstart', function (event) {
transform .transform.attach(picked);
