JSoup appears to generate an incorrect DOM in response to the (erroneous) input

<body>
  <video autoplay="" id="remote" width="240"/>
  <script>
    ...
  </script>
</body>

(The "/" in the video tag should be ignored; it should be treated as a start tag to be closed later.)

Chrome and Firefox, validator.nu and AngleSharp all put the script element as a child of the video element. JSoup leaves video and script as siblings.

Thanks - this is the same as #917 and #1037. See notes on the latter in particular. We will need to implement the idea on that to be able to resolve this, I believe. Unless there are other ideas?

Feel free to close as a duplicate. I quite agree that what JSoup is doing seems eminently reasonable in the circumstances, but we are more concerned with interoperability and conformance than with usability.

I will leave it open as the closest #1037 is closed, and this description is clear.

(On review, closing as dupe of #917. 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.)
