Buggy source:

}

Fixed version (ground truth):

  mInputLogicHandler.onStartBatchInput();
  handler.showGesturePreviewAndSuggestionStrip(SuggestedWords.EMPTY,false);
  handler.cancelUpdateSuggestionStrip();

  if (mWordComposer.isComposingWord()) {
    if (settingsValues.mIsInternal) {
      if (mWordComposer.isBatchMode()) {
        LatinImeLoggerUtils.onAutoCorrection("String_Node_Str",mWordComposer.getTypedWord(),"String_Node_Str",mWordComposer);
      }
    }
    final int wordComposerSize=mWordComposer.size();
    if (mWordComposer.isCursorFrontOrMiddleOfComposingWord()) {
      resetEntireInputState(settingsValues,mConnection.getExpectedSelectionStart(),mConnection.getExpectedSelectionEnd(),true);
    }
 else     if (wordComposerSize <= 1) {
      commitCurrentAutoCorrection(settingsValues,LastComposedWord.NOT_A_SEPARATOR,handler);
    }
 else {
