alt Hacker NewsI’m not sure this is correct. The DOM class HTMLDetailsElement has the `open` property, which you can use to read/write the details element’s state. If you’re using setAttribute/getAttribute just switch to the property.

Having to use the property on the element instance, rather than the actual HTML attribute, is exactly the kind of wrapper code I want to avoid if I'm using a built-in.
