Comment 20 for bug 1621340

I already pointed proper dep3 headers out in comment #4 - there is also a link on the spec.
But I missed when they got added that they were not complete.
Good catch Robie, neither me nor cyphermox saw that.

FYI - Comment #9 has the link to the commit.

Who is rerolling the patch - zhhuabj or you in a quick reupload cyphermox?
