/**
* A List displays a group of related sequential items.
*
* @accessibility
* List may follow one of the following accessibility semantics:
* - Static non-navigable list. Implements [ARIA list](https://www.w3.org/TR/wai-aria-1.1/#list) role.
* - Selectable list: allows the user to select item from a list of choices. Implements [ARIA Listbox](https://www.w3.org/TR/wai-aria-practices-1.1/#Listbox) design pattern.
* @accessibilityIssues
* [NVDA - Browse Mode does not work with listbox #12350](https://github.com/nvaccess/nvda/issues/12350)
* [JAWS - Listbox options are not reachable in Virtual Cursor PC mode #517](https://github.com/FreedomScientific/VFO-standards-support/issues/517)
* [JAWS - Aria-selected is not narrated for the single-select listbox, when selection is NOT moved with focus #440](https://github.com/FreedomScientific/VFO-standards-support/issues/440)
