BUG: select actions does not trigger "input" events (only "change" event) on select inputs/dropdowns

[cgaube]

Context

When a user change/select the value (option) of a dropdown input :

<label for="test">Trigger events</label>
<select name="test" id="test">
  <option>A</option>
  <option>B</option>
</select>

<script>
const selectInput = document.getElementById('test');

selectInput.addEventListener('change', () => console.log('CHANGE EVENT TRIGGERED));
selectInput.addEventListener('input', () => console.log('input EVENT TRIGGERED));
</script>

in test:

select 'B', from:"Trigger events" 

it does not trigger the input event , but correctly triggers the change event
https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/input_event

Looking at the code i think we are missing a line that also triggers a input event in addition to that change event

cuprite/lib/capybara/cuprite/javascripts/index.js

Lines 363 to 380 in c7dc979

	changed(node) {
	let element;
	let event = document.createEvent("HTMLEvents");
	event.initEvent("change", true, false);
	// In the case of an OPTION tag, the change event should come
	// from the parent SELECT
	if (node.nodeName == "OPTION") {
	element = node.parentNode
	if (element.nodeName == "OPTGROUP") {
	element = element.parentNode
	}
	element
	} else {
	element = node
	}
	element.dispatchEvent(event)
