vue3 I encountered a responsive variable used in the watchEffect function, but the watch is not triggered when the value changes. What is the problem?

ckend.js:8266 [Vue warn]: Avoid app logic that relies on enumerating keys on a component instance. The keys will be empty in production mode to avoid performance overhead.

From a logical point of view, the above code does not cause recursive trigger watch execution.

This statement data.newsDialog.currentNews is the trigger point, when the click event will assign the data.newsDialog.currentNews property.

是我功力太浅了，绕进去了。
