I don't know of a good term for it; it's some kind of heading.

I'm still having trouble figuring out what you think is wrong with groff
1.23.0 relative to 1.22.4.
$ nroff --version | sed 1q
GNU nroff (groff) version 1.23.0
$ /usr/bin/nroff --version | sed 1q
GNU nroff (groff) version 1.22.4
I took the `RP` call out of my document to dispose of the cover page and
tried my experiments again. With both versions of groff I get all of
the "document description info" (the term used by groff ms
documentation) on page 1 before the main matter, _except_ for the date.
I get diagnostics from both groff 1.22.4 and 1.23.0 ms if I use `LP`
between `AU` and `AB` calls, because `LP` caused the macro package to
decide the front matter/document description info was done. The
messages differ slightly in punctuation.
$ /usr/bin/nroff -rLL=65n -ms /tmp/LP-in-abstract-BAD.ms >/dev/null
/tmp/LP-in-abstract-BAD.ms:9: macro error: AB is not allowed after first AB,
LP, PP, IP, SH or NH
/tmp/LP-in-abstract-BAD.ms:21: macro error: AE without AB
$ nroff -z -ms /tmp/LP-in-abstract-BAD.ms
s.tmac:/tmp/LP-in-abstract-BAD.ms:9: error: .AB is not allowed after first .AB,
.LP, .PP, .IP, .SH or .NH
s.tmac:/tmp/LP-in-abstract-BAD.ms:21: error: .AE without .AB
I may have guessed wrongly at where you were using `LP` or `PP`.
Output differs only in a detail of adjustment.[1] (I gave 1.22.4 the
"-rLL=65n" parameter to conform to 1.23.0's new default line length.[2])

What's bad about the "BAD" example is that an `LP` in the "midst" of
`AU` author information causes subsequent material to format
incorrectly.

But it's same wrongness on 1.22.4 and 1.23.0 for me.
Can you share a reproducer? Sorry to be dense. :(
I'm attaching the inputs I used to produce the above, in case they are
of some help.
