Description

FastVScroll was updated to implement desktop.Mouseable and fyne.Draggable for click-and-drag scrolling, but the inner container.VScroll captures mouse events before the outer widget sees them. Drag events never reach FastVScroll.Dragged, so the feature has no effect.

Expected behaviour

Users should be able to click and drag content up/down to scroll, mirroring mobile/touch-screen behaviour.

Current behaviour

Drag events are consumed by the inner scroll container. The outer FastVScroll widget never receives MouseDown, Dragged, or DragEnd calls.

Suggested fix

Replace the current approach with a transparent drag-capture overlay layered on top of the scroll container, or intercept events at the renderer level. Alternatively, subclass container.Scroll directly to add drag handling internally.
