By “semantic nesting”, I mean that the 'Item' label and description are now siblings, which is preferable to the previous implementation, where the description node was a child of the label node. As a general principle, we should align DOM hierarchies with information hierarchies. An analogy: If I were using a bulleted list to describe a dog, I would not indent its breed as a second-level bullet beneath the bullet for its name, because a dog’s breed is not dependent/derived data from its name. Similarly, description is not dependent/derived from label, and so should not be nested in DOM. * fix: Reduce styled-components class permutations. https://www.joshwcomeau.com/css/styled-components/ * feat(Overlay): slide away from anchor based on position (#1322) * feat(Overlay): slide away from anchor based on position * fix: handle position changes when re-opening AnchoredOverlay * refactor: use js animation for slide to fix safari * fix: Tests were failing with Axe violations - https://dequeuniversity.com/rules/axe/4.1/aria-dialog-name - https://dequeuniversity.com/rules/axe/4.2/presentation-role-conflict - https://www.w3.org/TR/wai-aria-practices-1.1/examples/menu-button/menu-button-links.html First, 'Overlay's aren’t 'listbox'es, because (when used in 'DropdownMenu' or 'ActionMenu') they contain 'menuitem's, 'menuitemradio's, or 'menuitemcheckbox'es.

The main goal here is to prevent scrollbars from showing briefly when an
AnchoredOverlay
is opened. This can happen if theOverlay
portion ends up slightly outside the currently visible area upon creation, or because of the slide animation. There are two main changes to correct this behavioranchorSide
fromuseAnchoredPosition
all the way intoOverlay
. With this information, we can infer which direction theOverlay
should "slide" when it is opened. We always want to to start slightly overlapping the anchor and then move into position. Previous behavior had it always sliding "up", which is only desired if theOverlay
is positioned above its anchor. If not passed ananchorSide
, there will now be no slide animation.visibility
setting fromOverlay
. This was a bandaid to handle scenarios where theOverlay
contents would briefly flash before moving into the correct position. While settingvisibility
removed the main visible flash, it did not prevent scrollbars from flashing if the unpositioned content happened to overflow the current frame. The more correct solution here is to replace a fewuseEffect
withuseLayoutEffect
, which allowsAnchoredOverlay
to create theOverlay
, calculate position, and re-position theOverlay
before the browser paints.Closes #1231
