Tinymce需要一个根块元素，这是一个默认的段落，以便能够对内容进行样式化。因此删除这些段落只会导致所有内容被包裹到一个单独的段落中，因为tinymce***使用它作为根块元素。

Tinymce needs a root block element, which is a paragraph by default, in order to be able to style content. So removing those paragraphs will only result in all content being wrapped into one single paragraph because tinymce is forced to use this as root block element.
