Comment (by zieladam):

 > The issue with </br> is identical to with an unexpected </p>. These tags
 cannot contain HTML attributes and so return null.

 AFAIR closing tags can contain attributes. The
 [https://html.spec.whatwg.org/#before-attribute-name-state HTML spec] has
 this parsing path:


 Tag open state -> End tag open state -> Tag Name State -> before attribute
 name state -> attribute name state.

 I remember we've discussed that in context of the inline token / funky
 comments and decided not to expose them.
