The span element with those classes make it hard to handle other span elements in editing, so one of them(Apple-style-span) has not been produced since 2011( https://webkit.org/blog/1737/apple-style-span-is-gone/). Other classes will be also removed from Blink. Here is the discussion for intent to remove: https://groups.google.com/a/chromium.org/d/msg/blink-dev/OlgmGUvnMU4/9HMNXMjGCQAJ
