Description

原本是不会报错的，但是我用了这个方式，消除了另外一个js插件的控制台的警告

然后现在滚动的时候，控制台会报错，也许这是解决方案

我已经在我的开源项目中使用smooth-scrollbar，在此非常感谢，还望尽快修复。

DeepL Translation:

Originally it would not have reported an error, but I used this to remove the warning from the console of another js plugin

Then now when scrolling, the console will report an error, maybe this is the solution

I have used smooth-scrollbar in my open source project, thanks a lot here, also hope to fix it soon.

We have already turned off the passive events, see:

smooth-scrollbar/src/utils/event-hub.ts

Line 35 in 02a0d81

eventListenerOptions = supportPassiveEvent ? { passive: false } as EventListenerOptions : false;

[idiotWu]

Alright, I checked the default-passive-events package and found that they copy the original options using Object.assign(): https://github.com/zzarcon/default-passive-events/blob/664c0d25cdb81a4f78f589321e613971e8279cf8/src/index.js#L18-L24

So, we can probably solve this issue by defining the passive property as enumerable: true in our passive event support detection.

A patch is coming soon.

Fixed in v8.8.2.
