The destructor has an assertion for mTransferredPorts.IsEmpty(). As far as I can tell we aren't supposed to do anything with the transferred ports, so we can just work around that assertion.

Hey, it's great to see structuredClone() land in Firefox!

For the record, the failing WPT tests in html/webappapis/structured-clone/structured-clone.any.html are due to a bug I introduced in https://github.com/web-platform-tests/wpt/pull/30824, which was specific to the self.structuredClone() runner and worked fine with other uses of the structured clone algorithm. This is now being fixed in https://github.com/web-platform-tests/wpt/pull/31034.
