We are never seeing a dbl click event in android chrome when talkback is on. Vist the following html on a touch device in non talkback and with talkback enabled and see differences in the emitted events.

see attached screen shots of the logged events.

<!DOCTYPE html>
<html>
<body>
<div tabindex="-1" id="a">My First Heading</div>
<script>
function x(event) {
console.log(event.type, event)
};
document.getElementById("a").addEventListener('mousedown', x);
document.getElementById("a").addEventListener('mouseup', x);
document.getElementById("a").addEventListener('focus', x);
document.getElementById("a").addEventListener('blur', x);
document.getElementById("a").addEventListener('touchstart', x);
document.getElementById("a").addEventListener('touchend', x);
document.getElementById("a").addEventListener('touchcancel', x);
document.getElementById("a").addEventListener('click', x);
document.getElementById("a").addEventListener('dblclick', x);
const el = document.getElementById("a");
el.onpointerdown = x;
el.onpointerup = x;
el.onpointercancel = x;
</script>
</body>
</html>
