Neither query shows the reported problem in my environment on master (as of
today) or v14, so not sure

=# SELECT seg_in(numeric_out(round(31, 10000)));
seg_in
--------
3e1
(1 row)

=# SELECT seg_in(numeric_out(round(31,1000000)));
seg_in
--------
3e1
(1 row)

It's possibly relevant that this result is different from the "3.100000e+01"
which was shown in your backtrace. Since a few details of this report don't
agree with each other, I'm starting to wonder if some other relevant
details got lost along the way.
