- Implemented a focus wrapper and anchor node system to safely escort Tab traversal directly to list items, bypassing silent Scrollable background viewports.
- Clamped initial scroll offset calculations to prevent out-of-bounds focus rejections on initial load when selectedIndex is -1.
- Added boundary constraints (walls) to the item-level KeyEvent interceptors to prevent arrow-key navigation from dropping focus into the background container at the edges of the list.
- Preserved original Tab-to-exit scope traversal.
