Mac OS X 10.8.5 で Chrome (バージョン 30.0.1599.101) をプレゼンテーション モードでタッチ スクリーン対応テレビで遊んでいたところ、突然 div がドラッグ可能になりました。jquery や HTML5 仕様を介してドラッグ アンド ドロップ機能を有効にしていませんでしたが、何とか div をドラッグして画面上の任意の場所に配置することができました。それらを回転させてサイズを変更できます。ページを更新すると、この機能は停止しました。これがどのように可能になったかについてのアイデアはありますか?
以前に Dev Tools から「Emulate Touch Events」を有効にしていましたが、この機能が表示されたときに Dev Tools は開いていませんでした。また、Chrome MuliTouch 拡張機能をインストールしてからアンインストールしました。
