jsdom: Setting a script element's `src` attribute after insertion does not load the `src` target.
If you modify a script’s src attribute after the element has been attached, the target script is never loaded.
This example will always log false to the console:
script.js
window.script_executed = true;
runner.js
const jsdom = require('jsdom');
const window = jsdom.jsdom("").defaultView;
window.script_executed = false;
const script = window.document.createElement("script");
window.document.body.appendChild(script);
script.src = "script.js";
// assume script.js will load asynchronously
setInterval(() => {
console.log(window.script_executed);
}, 1000);
A comparable script that executes in a browser and logs true:
<html>
<body>
<script type="text/javascript">
window.script_executed = false;
var script = window.document.createElement("script");
window.document.body.appendChild(script);
script.src = "script.js";
setInterval(function() {
console.log(window.script_executed);
}, 1000);
</script>
</body>
</html>

I don’t think further testing is helpful here. It’s clear that there are implementation bugs in resource loading with regard to attributes changing. I’ll spend some time fixing them.
