Description

When users interact with the "Expand All" or "Collapse All" buttons above the tree view component, no announcement is made by screen readers to indicate the change in the tree's state.
This lack of feedback prevents users relying on screen readers from knowing whether their action was successful and if the tree view's state has changed.
