Is this SFC invalid?

link: playground

got error:

(12:17) Invalid end tag.

I think <div> should be treat as a custom block. I found the custom root start tag can not contain the same-name tag inside it. Is it designed like this or it is a bug?

[lovetingyuan]

I think custom block should be treat as a single element, but it's content should not be parsed as html syntax.
like this

<custom> this is content </custom>, not html content </custom>

The two end tags will conflict with each other. I think the last end tag should take effect.

The offical @vue/compiler-sfc will handle custom block first, the error has already happend.
