 [Programmatically hidden](#programmatically-hidden) elements are removed from the accessibility tree. However, some browsers will leave [focusable](#focusable) elements with an `aria-hidden` attribute set to `true` in the accessibility tree. Because they are hidden, these elements are considered **not** included in the accessibility tree. This may cause confusion for users of assistive technologies because they may still be able to interact with these focusable elements using sequential keyboard navigation, even though the element should not be included in the accessibility tree.
