- [x] 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 3.1.0 ### Environment `ant-design-vue@3.1.1`, `vue@3.2.33` ### Reproduction link [![Edit on CodeSandbox](https://codesandbox.io/static/img/play-codesandbox.svg)](https://codesandbox.io/s/prod-cloud-yh4y5n?file=/src/App.vue) ### Steps to reproduce 1. Follow "Getting Started" steps to create `antd-demo` from [antdv.com](https://www.antdv.com/docs/vue/getting-started) 2. Paste the 1st code example from [antdv.com - components - form](https://www.antdv.com/components/form/#Form-Item-Component) into App.vue or any SFC ```vue ``` 3. Check console for warning: ``` [Vue warn]: Failed setting prop "size" on : value 0 is invalid. Error: Failed to set the 'size' property on 'HTMLInputElement': The value provided is 0, which is an invalid size. ``` 4. Downgrading to `ant-design-vue@2.2.8` will remove console warning ### What is expected? Input component should work without warning. ### What is actually happening? ``` [Vue warn]: Failed setting prop "size" on : value 0 is invalid. Error: Failed to set the 'size' property on 'HTMLInputElement': The value provided is 0, which is an invalid size. ``` --- Warning only occurs with ``. In the case of `textarea` (from [here](https://www.antdv.com/components/form/#components-form-demo-lable-width)), `` will also produce console warning. Using `` instead will not. This occurs in any version > 3.0.

Input component causes warning: "Failed setting prop "size" on <input>: value 0 is invalid" #5509
