- * Keep vertical wheel scrolling inside a scrollable widget container instead of
- * letting ComfyUI zoom the canvas.
- *
- * In Nodes 2.0 / Vue mode ComfyUI's wheel→zoom handler runs on the document /
- * canvas in the capture phase, which is *outer* than the widget, so a listener
- * on the container (even in capture) fires too late. The reliable place to win
- * is a single hook on `window` in the capture phase — the very first step of
- * event dispatch. When the wheel is over a marked, scrollable element we scroll
- * it manually and fully consume the event; otherwise we leave it alone so canvas
- * zoom keeps working.
