As we have 'pointer-events:none' for disabled items. Could you please change this selectors to:
section[role="region"] > header:first-child a:active:after,
section[role="region"] > header:first-child button:active:after,
section[role="region"] > header:first-child a:hover:after,
section[role="region"] > header:first-child button:hover:after
(same for skin-dark and skin-organic) ;)
