Insert position from insertAdjacentHTML seems wrong

[nielsdos]

What is the issue with the HTML Standard?

I'm implementing steps from https://html.spec.whatwg.org/#dom-element-insertadjacenthtml

At step 6 (Use the first matching item from this list) we see the following:

If position is an ASCII case-insensitive match for the string "afterend"

Insert fragment into this before its first child.

However, "afterend" is supposed to insert the contents after this, no?
Similarly, the step from "beforeend" seems wrong too.
Are these two swapped?

EDIT: The step for "afterbegin" seems wrong too, as it would add the new nodes after all other children.

@lukewarlow would you be able to take a look at this?

Yeah some of these do appear to have been switched around inadvertently.
