### `assert_object_equals(actual, expected, description)`
+**DEPRECATED**: see [issue #2033](https://github.com/web-platform-tests/wpt/issues/2033).

asserts that `actual` is an object and not null and that all enumerable
properties on `actual` are own properties on `expected` with the same values,
recursing if the value is an object and not null.
