3.32.1 breaks structuredClone fallback #1288
Description
Reproduction case:
<html>
<body>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/index.js"></script>
<script>
img = new Image();
img.onload = () => {
createImageBitmap(img).then(bmp => structuredClone(bmp));
};
img.src = "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAQAAAC1HAwCAAAAC0lEQVR42mP8zwQAAgYBAyKDV6YAAAAASUVORK5CYII=";
</script>
</body>
</html>Throws DOMException: Cloning of ImageBitmap cannot be properly polyfilled in this engine but doesn't on 3.32.0. I've tested on FF 117 and Safari 16.6.
It seems that changing != 7 to !== 7 in
structuredClone(Object(7)) == 7 but not ===. This disables the fallback to native structuredClone and prevents it from working when it should.
