Removing this tests because are no longer valid. Instead of applying 'styles' per each element, we use 'conditional css' for applying the right styles as you can see https://github.com/mozilla-b2g/gaia/pull/15256/files#diff-5cb1917b2f34c7e6ca11361714b980a7R208 .

We need to ensure that `data-state` is in the DOM, that's why I've added this to the tests here https://github.com/mozilla-b2g/gaia/pull/15256/files#diff-d7ceb741d23f1f5c4e988d54ca59c007R56
