自動サイズ変更プラグインでTinymceエディターを使用しています。私の問題は、tinymceインスタンスが初期化されたときに、コンテンツの高さをラップするために正しくサイズ変更されないことです。
エディターに長いテキスト（例15行）がある場合、tinymceが表示されると、5行のみのサイズ変更エディター領域が自動サイズ変更され、他の10行は表示されません。エディター領域に何かを入力した場合にのみ、15行すべてに対して自動サイズ変更が拡大します。
これはjavascript自動サイズ変更プラグインです：

しかし、タイマーソリューションは高さが小さいため、美しくはありません。そのため、400ミリ秒後にtinymceコンテンツ領域は正しく自動サイズ変更されます。代替ソリューションは存在しますか、またはどうすれば修正できますか？
