Product: axe-core

Expectation: wbr and br elements only allow the none and presentation roles. And only allow the aria-hidden attribute.

Actual: br presently allows any global aria- attribute. wbr presently allows for any role and global aria-* attribute, or aria-* attribute applicable to the assigned explicit role.

role test page for wbr

Motivation: ARIA in HTML will be changing the allowances for br and wbr elements. These elements will only allow the none and presentation roles, and the aria-hidden attribute. Other roles and global aria- attributes do not make sense to be used on these elements, particularly due to their inability to be effectively modified by authors.
