TkinterでWindowsのNotepadのような物を作りたい(ですが、検索ボックスが出てくる原因が不明です)

いつも、お世話になっております。

リンクを参考に、Tkinterを使用して、Windowsで言うところのNotepad的なGUIを作りたいと考えております

下記がコードなのですが、Macで実行すると、画像のように検索がVersionとAboutの上に出てきます
コードのどの部分が、Searchを表示しているのか、判断がつかないので、ご教授お願いします

開発環境
Mac: macOS Catalina バージョン10.15.1
Python: 3.7.5
Tkinter: 8.5(使用したコマンド $python3 -m tkinter)
