¿Por qué JavaScript prohíbe combinar el operador nulo (??) con los operadores And (&&), OR (||)?

¿Por qué JavaScript lo prohíbe (da un error de sintaxis), si el operador nulo (??) se combina con los operadores Y (&&), O (||) "sin paréntesis"?

Ejemplo:

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

Pero siguiendo obras

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