It must be a bug when the loader resolves `@import url()`. I will fix this. Thanks for reporting.

Actually it's not a problem. Statements like `@import url('https://fonts.googleapis.com/css?family=Karla:400,700|Rubik:400,500,700')` is not preferred to inject into all style files, they may be imported only once.

@clark-t 现在 validator 有一条规则，input 的祖先必须有 mip-form 元素
