ARIA (Accessible Rich Internet Applications) is a set of attributes that define ways to make web content and web applications more accessible to
people with disabilities. The aria-hidden attribute is used to indicate that an element and all of its descendants are not visible or
perceivable to any user as implemented by assistive technologies.
However, when aria-hidden is used on a focusable element, it can create a confusing and inaccessible experience for screen reader
users. This is because the element will still be included in the tab order, so a screen reader user can navigate to it, but it will not be announced
by the screen reader due to the aria-hidden attribute.
This rule ensures that focusable elements are not hidden from screen readers using the aria-hidden attribute.
