Livejournal Service Question: Spell Checker?

Does anyone know what happened to Livejournal's "spell checking in comments" function?

I tend to heavily rely on that one, mostly because I'm one of the worst typists who ever sat in front of a keyboard. And for the last couple of days I've been noticing that instead of marking any misspelled words, pushing the preview/spell check button only leads to rendering the whole comment in bright red.

Please tell me there's a way to revert this glitch back to normal...
