html: Fix assert_array_equals usage in pseudo-classes

document.querySelectorAll returns a NodeList, which does not have a .slice method that assert_array_equals uses. This fixes dir.html on Firefox, which supports the :dir pseudo-class.

CI Results

Ran 13 Firefox configurations based on mozilla-central, and Firefox, Chrome, and Safari on GitHub CI

Total 56 tests
