Comment 7 for bug 1335002

I think the original issue here is that after initially switching to Chinese from another language, if you're already in a field then the candidate bar doesn't appear until after you've typed the first character (and that first character then doesn't get included as part of the prediction).

We definitely need to improve the predictions offered by libpinyin (or try using a different pinyin suggestion engine), but I think that's a separate issue.
