I wanted to use structuredClone in browser/components/sessionstore/test/unit/test_shutdown_cleanup.js but I get an error.

ERROR Unexpected exception ReferenceError: structuredClone is not defined at C:/Users/Mathew/source/repos/mozilla-central/obj-x86_64-pc-mingw32/_tests/xpcshell/browser/components/sessionstore/test/unit/test_shutdown_cleanup.js:46

I figured out that it can be used by first calling Cu.importGlobalProperties(["structuredClone"]), but there aren't any uses in the tree currently, so I think we should add a test for this.
