What problem does this feature solve?

I have a project that use @vue/compiler-sfc to parse vue sfc component and transform some nonstandard code and regenerate them. But @vue/compiler-sfc will parse html5 self closing tags to a AST node with isSelfClosing = false, such as img:

<img :src="icon.url">

the isSelfClosing attribute in AST is false, so that it will be transformed incorrectly when regenerate new code like that:

<img :src="plan.icon"></img>

According to the HTML5 spec, tags that cannot have any contents (known as void elements) can be self-closing*. This includes the following tags:

area, base, br, col, embed, hr, img, input, 
keygen, link, meta, param, source, track, wbr

What does the proposed API look like?

The isSelfClosing attribute in AST to be true when parse html5 self closing tags.
