According to the w3 combobox accessibility best practices, combobox suggestions should have a aria-selected="true" attribute on the li element when a suggestion is visually highlighted (e.g. when a user navigates through the suggestions with the up/down arrow keys).
However, WVUI search suggestions are currently missing this attribute.
- When a search suggestion is highlighted by navigation with the up/down arrow keys, the aria-selected="true" appears on the li element.
- When a search suggestion is not highlighted, aria-selected="true" should not appear on the li element. It should also not appear when the user hovers over the search suggestion using their mouse per T287775#7281906.
