Почему ломается wp_editor в виджете после сохранения?

Question

[Алексей Верховцев]

Всем привет, смог запустить нормально wp_editor в виджете с помощью данного способа Но в итоге после нажатия сохранить у меня редактор рушится, пропадают все кнопки управления TinyMCE, а при нажатии на Visual выдает такое Uncaught TypeError: Cannot read property 'canvas' of undefined. Кто-нибудь сталкивался? Заранее спасибо

Код виджета
