Applying NOT twice on an integer in WHERE condition leads to incorrect results.

When applying NOT twice to an integer in WHERE condition, the result is incorrect.
How to repeat:

CREATE TABLE t(a INT);

INSERT INTO t VALUES (-1);

SELECT * FROM t WHERE (NOT (NOT (a))) = -1; -- [-1]

SELECT (NOT (NOT (a))) FROM t; -- [1]

The same expression yields inconsistent results when appearing in the WHERE condition and projection list. I believe that the result of applying NOT twice to an integer should be 1 or 0 rather than the original value.
