3. Set input method to Hiragana
4. Type in a field (IE: jaaka which produces じゃあか) and do not select a prediction

6. Click in any field and type a single character

* EXPECTED RESULTS

We lost the code to call -discardMarkedText in async text input code path (and before that, some of it got lost in <http://trac.webkit.org/changeset/150291>). That was intentional, but of course we do need to call it in this case, and also on navigation.
