Previously, has_scrollable_overflow was a purely geometric check, true whenever content extended beyond the padding box regardless of the overflow property. This caused unnecessary scroll frame allocation for boxes with `overflow:visible`. Per CSS Overflow 3, scrollable overflow is only defined for scroll containers (overflow: auto/hidden/scroll). Gate the flag on `is_scroll_container()` so that only actual scroll containers get scroll frames assigned.
