The hit-testing position is now shifted by the scroll offsets before performing any checks for containment. This is implemented by assigning each PaintableBox/InlinePaintable an offset corresponding to the scroll frame in which it is contained. The non-scroll-adjusted position is still passed down when recursing to children because the assigned offset accumulated for nested scroll frames. With this change, hit testing works in the Inspector. Fixes https://github.com/SerenityOS/serenity/issues/22068
