Why JavaScript forbids combining Nullish operator (??) with And (&&), OR (||) operators?

Question

Why JavaScript forbids it (gives syntax error), if Nullish operator (??) is combined with And (&&), OR (||) operators "without parenthesis"?

Example:

let x = 1 && 2 ?? 3; // Syntax error

But following works

let x = (1 && 2) ?? 3; // Works
alert(x);
