Push Members Down: again some formatting issues when I try to do reformatting

  private void reformat(final PsiMember movedElement) {
    ApplicationManager.getApplication().runWriteAction(new Runnable() {
      @Override
      public void run() {
        final TextRange range = movedElement.getTextRange();
        final PsiFile file = movedElement.getContainingFile();

        PsiDocumentManager psiDocumentManager = PsiDocumentManager.getInstance(myProject);
        psiDocumentManager.doPostponedOperationsAndUnblockDocument(psiDocumentManager.getDocument(file));

        final PsiFile baseFile = file.getViewProvider().getPsi(file.getViewProvider().getBaseLanguage());
        CodeStyleManager.getInstance(myProject).reformatText(baseFile, range.getStartOffset(), range.getEndOffset());
      }
    });
  }

Same code works somehow for Pull Members Up.
