 Several major browsers ignore the WAI-ARIA requirements on [presentational children][] for most or sometimes all roles, or in presence of focusable content. Since some browsers implement presentational children while others do not, pages failing this rule may only be problematic with some browsers.
 
-This rule is often misunderstood as applying to elements with an _explicit_ role of `presentation`. In fact, this rule only applies to elements which have been given an _implicit_ role of `presentation` through the [presentational children][] mechanism. Similarly, this rule does not apply to elements with `aria-hidden="true"`.
