When I type gibberish into the topic-title text-area, the wavy red underline of spellcheck doesn't appear. It does work for the post text-area.
This is in Firefox. context menu has Check spelling and if you enable it then spelling starts working. Not sure whether pages can affect this.
https://support.mozilla.org/en-US/kb/how-do-i-use-firefox-spell-checker says "Firefox automatically checks the spelling of words that you enter in text boxes containing more than one line." So this is a browser quirk, and not a bug at our end. Closing as invalid.
