Reproduction Link

Steps to reproduce

What is Expected?

throw a warning or an error

What is actually happening?

Although this case works well. But the result is not expected. And there are no any warning or error displayed so that it is very difficut to find the template mistake.

I'm looking into it. Maybe we could improve the parser, or we could achieve it in vue-loader and vueify considering the compiler code size.

@defcc have you considered using DomParser?

Example:
document.body.innerHTML = new DOMParser().parseFromString('<div></p></div>', 'text/xml').documentElement.innerHTML
