selector not work when use uppercase node name #3612
Description
Basic info:
- Node.js version: v20.6.1
- jsdom version: 22.1.0
Minimal reproduction case
test("check jsdom uppercase nodeName", () => {
const mockDocument = new JSDOM(`
<!DOCTYPE html>
<html lang="en">
<body>
<h1>test mask solution</h1>
<div class='box'>
<div>
<p id="p1"></p>
<p id="p2"></p>
</div>
</div>
</body>
</html> `);
const { document } = mockDocument.window;
const result = document.querySelector("div.box");
expect(result).not.null;
const result1 = document.querySelector("DIV.box");
expect(result1).to.null;
});if I use div.box then the result was expected, but DIV.box yield a null
How does similar code behave in browsers?
works in both case
(Link to a jsbin or similar strongly suggested.)
