Description

See https://stackblitz.com/edit/js-gxcyih?file=index.js

I think it's because of the way we fall into the "plain" object comparison in https://github.com/lukeed/dequal/blob/master/src/index.js#L73-L80

```javascript
const x = new URLSearchParams();
x.append("foo", "bar");

for (i in x) {
if (x.hasOwnProperty(i)) console.info(i);
}
```

=> Nothing gets printed because e.g. `entries` is always the same, but the stuff returned from `entries` is not.

Research direction

Start with the URLSearchParams reproduction in the linked StackBlitz example, then inspect the plain-object comparison around src/index.js lines 73-80. Confirm the behavior for URLSearchParams instances and add or update coverage so comparisons reflect their contents rather than only their enumerable properties.
