NodeList.forEach drops an explicit null callback context

Description

NodeList.forEach treats both null and undefined as the omitted thisArg fast path. An explicitly supplied null is therefore discarded, and a strict callback receives undefined instead of null, unlike standard Array and NodeList behavior.

Expected behavior

Only an omitted/undefined thisArg should use the unbound callback path. Explicit null should be forwarded as the callback receiver.

从 NodeList.forEach 的实现开始，跟踪 null 和 undefined 的 thisArg 值是如何处理的。为显式设置为 null 的回调上下文添加或更新覆盖率，然后验证 strict 回调接收到 null，而省略的或设置为 undefined 的上下文保留现有行为。
