/**
 * Whether an element is currently scrolling its content.
 *
 * Exists because "is this scrollable" decides an accessibility fact, not a
 * cosmetic one: axe's `scrollable-region-focusable` wants a scrolling box in the
 * Tab order so a keyboard user can reach the content Safari will not scroll for
 * them, and a box that fits must stay out of it or every short list becomes a
 * focus stop before its own controls. That answer changes with content, zoom, and
 * container width, so it is observed rather than assumed.
 *
 * Shared by `ScrollRegion` and `ScrollArea`, which put the answer on different
 * elements: `ScrollRegion` is the scrolling box, while `ScrollArea`'s box belongs
 * to Radix and can only be reached by ref.
