What steps will reproduce the bug?
structuredClone({}, {
transfer: {
*[Symbol.iterator]() {}
}
})or
new MessageChannel().port1.postMessage({}, {
transfer: {
*[Symbol.iterator]() {}
}
})How often does it reproduce? Is there a required condition?
No response
What is the expected behavior? Why is that the expected behavior?
this should work and return an empty object
What do you see instead?

The webidl states that a sequence is basically anything with a Symbol.iterator, not exclusive to arrays. https://webidl.spec.whatwg.org/#es-sequence
