Interop 2024: Chrome at 100% for the accessibility focus area

As with every focus area in Interop 2024, the accessibility area is defined by a set of web platform tests for selected features. The tests in Interop 2024 aim to ensure all browsers create accessible names and computed roles in the same way. Accessible names convey the purpose or intent of an HTML element. This helps users understand what the element is for and how they can interact with it. The accname specification defines how browsers create this accessible name string for an element. The ARIA specification includes a walkthrough of how this name is calculated. The computed role of an element is a string that represents the role of the element as computed by the browser engine. This is used primarily in developer tools and, for example, in the WebDriver function getComputedRole, enabling interoperability testing.
