Self closing field should be ignored for tags that aren't self closing per spec

[EasonShi]

example

<a />content</a>
Parsed into
<a></a>content

@EasonShi, what would you expect the output to be?

Actually I looked at this the other day but forgot to add my notes. The spec and Chrome will ignore the self-closing flag. (So it would parse as <a>content</a>.) It looks like the spec has changed a bit since I implemented it, or that I missed the note, that an invalid self-closing flag should be rejected, and not just emitted as an error.

Need to check what impact that has as a behavior change.

Are there any news when this is going to be fixed?

I am thinking of addressing this by renovating how we hold properties in Tags, and allow configuration of self-closing / void tags. And then moving the HTML default back into spec.

Planning on changing this to align to the spec once #2285 Custom Tags is done
