Minifier: #__PURE__ marked optional chain expression with side-effect in arguments

[KermanX]

Current behavior:

/*#__PURE__*/ unknown?.(effect()) // =====> effect();

If unknown is nullish, in the original code, effect() won't be called, but in the output code, it will.

Expected behavior:

The output should be either:

• Preserve the original code
• unknown !== null && unknown !== undefined && effect()
