Steps to reproduce

1. Create a set with Proxy, such as ref(new Set([...]))
2. Call Set#intersection

What is expected?

It shouldn't throw an error

What is actually happening?

It throws error: "Set operation called on non-Set object"

System Info

Vue: fd5c001
TypeScript: 5.5.3

Any additional comments?

There is a workaround: toRaw(mySet.value).intersection does not throw error.

Looks like this issue also applies to some other Set methods:

• difference
• isSubsetOf
• isSupersetOf
• isDisjointFrom
• symmetricDifference
• union

Your version linking to 3.4.32 release note made me think it's a regression, but it seems the behavior has always been like this since Vue 3?

[sevenc-nanashi]

I can reproduce this issue in Vue 3.2, 3.3 too.
Somehow I couldn't run the code in that playground in Vue 3.0 and 3.1 (even though @vue/compiler-sfc was installed), so I haven't checked that.

我想问一句，set的原生方法intersection不支持带proxy的set，这不是很正常吗？为啥要提issue，而且还有人给解决了？我理解，框架不是自有一套逻辑，为啥要这样兼容各种看似跟框架设计不一样的问题呢，谁能解答一下
