### Fix for nested scrollable areas

This implementation has been added in order to fix an issue where scrollable content was unreachable. If a scrollbar is set to `display: none;` or `width: 0;` then the scrollbars of nested scrollable areas would be stacked on top of each other meaning that some of the content may well be unreachable. This does however mean that the `@supports selector(::-webkit-scrollbar)` check will return `true` even though the [`::-webkit-scrollbar`](/en-US/docs/Web/CSS/Reference/Selectors/::-webkit-scrollbar) pseudo-element is not truly supported. ([Firefox bug 1977511](https://bugzil.la/1977511)).

### `<timeline-range-name>` values

The {{cssxref("animation-range-start")}}, {{cssxref("animation-range-end")}} CSS properties and {{cssxref("animation-range")}} shorthand property now support [`<timeline-range-name>`](/en-US/docs/Web/CSS/Reference/Values/timeline-range-name) values. These [`<timeline-range-name>`](/en-US/docs/Web/CSS/Guides/Scroll-driven_animations/Timeline_range_names#timeline_range_names) values allow you to precisely state which segment that a scroll driven animation will take place within.
