Summary

Live Region: The role "alert" is only output if visibility is changed (Chrome)

  1. save as HTML file:
<!DOCTYPE html>
<html lang="en">
	<head>
		<meta charset="utf-8">
		<title>live region</title>
	</head>
	<body>
		<div id=1 hidden role=alert>role=alert</div>
		<div id=2 hidden aria-live=assertive>aria-live=assertive</div>
		
		<button onClick="document.getElementById('1').removeAttribute('hidden');">remove hidden 1</button>
		<button onClick="document.getElementById('2').removeAttribute('hidden');">remove hidden 2</button>
		<button onClick="document.getElementById('1').innerHTML='changed 1';">change 1</button>
		<button onClick="document.getElementById('2').innerHTML='changed 2';">change 2</button>
	</body>
</html>
  1. Press all buttons one after the other

Expected result

  • Consistent output between browsers
  • role=alert is always or never output as alert
  • role=alert is otherwise output like aria-live=assertive

Actual result with Chrome

  • Change of visibility at role=alert: Output of message with addition "alert"
  • Change of visibility at role=assertive: No output
  • Change of content at role=alert: Output of message without addition "alert"
  • Change of content at role=assertive: Output of message
  • Different output with IE 11 and Firefox
