I'm quite surprised that you aren't even getting the warning due to
`eqn -Thtml`.

I was running

        $ troff --version
        GNU troff (groff) version 1.23.0.902-1fce7-dirty

But I can reproduce it with 1.23.0:

        $ /usr/bin/groff --version | head -n1;
        GNU groff version 1.23.0
        $ diff -u0 \
                <(/usr/bin/preconv man3/_Generic.3 \
                        | /usr/bin/tbl \
                        | /usr/bin/eqn -Tps \
                        | /usr/bin/troff -man -Thtml -Wbreak \
                        | /usr/bin/post-grohtml) \
                <(/usr/bin/preconv man3/_Generic.3 \
                        | /usr/bin/tbl \
                        | /usr/bin/troff -man -Thtml -Wbreak \
                        | /usr/bin/post-grohtml);
