- [ ] I have searched the [issues](https://github.com/vueComponent/ant-design-vue/issues) of this repository and believe that this is not a duplicate. ### Version 4.2.6 ### Environment 官网即可复现 ### Reproduction link [https://www.antdv.com/components/select-cn](https://www.antdv.com/components/select-cn) ### Steps to reproduce 你把官网的自动分词里面的options 改为一个空数组,然后做自动分词的操作,按下enter键,即可复现bug,按照现实需求,在需要自动分词的需求中基本不会说要带一个默认值 options=[{label:'a', value: 'a'}],现实的需求中 默认值基本就是一个空数组。这个设置为一个空数组的时候,按下enter键就会发生删除效果。 ### What is expected? 按enter 键不会删除东西 ### What is actually happening? enter键会删除生成的tag项 <!-- generated by issue-helper.
