                OS: Unspecified

Safari behavior tested

Create this page and see that the click event is not triggered when using normal nor accessible ways of choosing options:

<!DOCTYPE html>
<html>
<body>
<h1>Onclick select test</h1>
<label for="select">Select an option:</label>
<select id="select">
<option value="1">One</option>
<option value="2">Two</option>
</select>
<div>Total number of onclick events: <span id="output">0</span></div>
<script>
const select = document.getElementById("select");
const output = document.getElementById("output");
select.addEventListener("click", function() {
output.textContent = parseInt(output.textContent) + 1;
});
</script>
</body>
</html>

What Chromium browsers do is trigger the click event for select elements whenever an option is selected. This includes triggering the event when selection is made using the keyboard. When to fire it is arguable: you could argue it should fire both when opening the select and selecting an option, though I feel that's less useful and that doesn't match Chromium behavior. However, it should not never fire, and it currently doesn't in Safari.
