Unfortunately, (even tough we're the last implementor of this feature`,) there are not editing behavior tests in web-platform tests. Therefore, this patch creates new `plaintext-only` directory into `editing` and make the feature enabled in its `__dir__.ini` to check the implementing behavior with new tests. This patch also changes how to compute the editing host (whether using `<body>` or not when selection is outside it), but the new behavior (not limited in the `<body>`) should work fine in the most cases and I believe that it's better than current implementation in some methods. Note that Chrome considers whether the style should be updated or not with the closest inclusive ancestor of the **focus node** of `Selection`. However, it's odd and aligning to the behavior requires bigger change. Therefore, I'd like to implement this feature only with checking the focused editing host.
