Buggy source:

    }
  }
  final InputConnection ic=getCurrentInputConnection();
  if (ic != null) {
    ic.beginBatchEdit();
  }
  TextEntryState.acceptedSuggestion(typedWord,suggestion);
  try {
    if (mCompletionOn && mCompletions != null && index >= 0 && index < mCompletions.length) {

Fixed version (ground truth):

    if (index == 0) {
      suggestion=typedWord;
    }
 else {
      getQuickKeyHistoryRecords().store(suggestion.toString(),suggestion.toString());
    }
  }
  final InputConnection ic=getCurrentInputConnection();
  if (ic != null) {
    ic.beginBatchEdit();
  }
  TextEntryState.acceptedSuggestion(typedWord,suggestion);
  try {
    if (mCompletionOn && index >= 0 && index < mCompletions.length) {
      CompletionInfo ci=mCompletions[index];
      if (ic != null) {
        ic.commitCompletion(ci);
      }
      mCommittedWord=suggestion;
      if (mCandidateView != null) {
        mCandidateView.clear();
      }
      return;
    }
    commitWordToInput(suggestion,false);
    TextEntryState.acceptedSuggestion(mWord.getTypedWord(),suggestion);
