- * We're skipping this test due to JSDOM issue:
- * https://github.com/jsdom/jsdom/issues/2961
- *
- * It should pass on Node >= 12.0, but since the core library
- * is expected to run on Node >= 10.0, and this test only applies
- * to the demo project, it's better disabling it for now than
- * getting false negatives.
- *
- * When this test is eventually re-enabled, don't forget to remove
- * the `remove-me` text at the top of this file to re-enable the
- * loading of jsdom.
