富文本p标签 自动添加，如何修改

#### 实现场景：
富文本Rich Text组件中，使用该组件时，自动添加p标签，采用设置options下的forced_root_block=“”时，无法生效

#### 存在的问题：
请告知我一下这个设置如何使用，我看了TinyMCE的文档是在init中加入这个属性的

Start at the Rich Text component and trace how its options are passed into the TinyMCE initialization described in the issue. Reproduce the automatic p-tag insertion with forced_root_block set to an empty value, then verify whether the option is supported and document or correct the configuration so the intended behavior is clear.
