I got around to trying this today, and I can't reproduce it either.
I get the expected behavior when running pg_restore's output through
psql --- all three commands execute, with the middle one failing:

...
REVOKE
ERROR:  role "user1" does not exist
GRANT

mzj_test=# \dp
                             Access privileges
 Schema |  Name  | Type  | Access privileges | Column privileges | Policies
--------+--------+-------+-------------------+-------------------+----------
 public | table1 | table | =a/postgres       |                   |
(1 row)

while if I try to run the pg_restore direct to database, all three
commands fail because they're implicitly grouped into one transaction:

pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 3058; 0 0 ACL TABLE table1 postgres
pg_restore: [archiver (db)] could not execute query: ERROR:  role "user1" does not exist
    Command was: REVOKE ALL ON TABLE public.table1 FROM postgres;
GRANT INSERT ON TABLE public.table1 TO user1;
GRANT INSERT ON TABLE public.table1 TO PUBLIC;

WARNING: errors ignored on restore: 1

mzj_test=# \dp
                             Access privileges
 Schema |  Name  | Type  | Access privileges | Column privileges | Policies
--------+--------+-------+-------------------+-------------------+----------
 public | table1 | table |                   |                   |
(1 row)


The latter behavior is not great, probably, but it's acting as designed.

As for Moshe's different results when going through psql, the only
theory that comes to mind is that he's got it configured with
ON_ERROR_STOP turned on, probably in ~/.psqlrc.
