After recent IME work landed, we don't dispatch composition events, but we depend on that in FormAssistant to show autocomplete suggestions.

Alex - Can you see if we should still be firing composition events. If not, should we be firing other key events and/or input events?

We do fire the NS_TEXT_TEXT event, but there is no corresponding nsIDOM* object, so it's visible as a simple UIEvent in JS.

I've been looking at an option to fire composition events. They trigger some input handling logic, which causes unwanted side-effects with this new approach. I'll make another try, as apparently composition events are important.

This patch fixes the issue.
I don't really like this approach - it causes NS_COMPOSITION_START and NS_COMPOSITION_END events to be sent on every character, but it works, so can be used, at least as a short-term solution.
I'll continue looking into this.
