[GENERAL] SELECT FOR UPDATE violates READ COMMITTED isolation?

I have this table:

CREATE TABLE test (id INT PRIMARY KEY);
INSERT INTO test VALUES (1);

Then I run these two transactions simultaneously:

one                            | two
-------------------------------+-------------------------------
BEGIN;                         |
                               | BEGIN;
DELETE FROM test; --DELETE 1   |
                               | SELECT * FROM test FOR UPDATE; -- Blocks...
INSERT INTO test VALUES (1);   |
COMMIT;                        |
                               | -- ...returns 0 rows

How is it possible that the select in transaction two returns 0 rows? There was
never a transaction that committed with 0 rows in test. Shouldn't read
committed isolation prevent this?

I think this paragraph explains why it happens:
https://www.postgresql.org/docs/9.6/static/transaction-iso.html#XACT-READ-COMMITTED.

How is that allowed in READ COMMITTED? I never committed with 0 rows in test,
so I expected to never have a SELECT that returns 0 rows.
