Many tests are failing due to self-closing tags in HTML

[Aloisius]

It looks like #250 started self-closing void tags like <img> tags which broke a whole bunch of tests.

Self-closing tags (<tag />) do not exist in HTML. While it's explicitly ignored in HTML5, it's technically invalid in HTML4 though in practice parsers ignore it. Either the change should be reverted or all the tests should be fixed.

Perhaps a GitHub Action should be setup to test builds during pull requests/push?
