Summary

Live Region: Inconsistent interpretation of "changed node" with aria-atomic=false

  1. save as HTML file:
<!DOCTYPE html>
<html lang="en">
	<head>
		<meta charset="utf-8">
		<title>live region</title>
	</head>
	<body>
		<div id=1 role=log aria-atomic=false></div>
		<button onClick="document.getElementById('1').innerHTML='1 2';">1a</button>
		<button onClick="document.getElementById('1').innerHTML='1 2';">1b</button>
		<button onClick="document.getElementById('1').innerHTML='<span>1 2</span>';">2a</button>
		<button onClick="document.getElementById('1').innerHTML='<span>1 2</span>';">2b</button>
		<button onClick="document.getElementById('1').innerHTML='<span>1</span> <span>2</span>';">3a</button>
		<button onClick="document.getElementById('1').innerHTML='<span>1</span> <span>2</span>';">3b</button>
		<button onClick="document.getElementById('1').innerHTML='<div><span>1</span> <span>2</span></div>';">4a</button>
		<button onClick="document.getElementById('1').innerHTML='<div><span>1</span> <span>2</span></div>';">4b</button>
	</body>
</html>
  1. Activate all buttons one after another

Expected result

Actual result

  • Firefox: output with all buttons
  • IE 11: output with all buttons (with long reading pause beetwen 1 and 2 at button 3a and 3b)
  • Chrome: output only with buttons 1a, 4a, 4b (span is not considered as a node, but div)
