/**
* Runs a collection of tests that determine if an API implements structured clone
* correctly.
*
* The `runner` parameter has the following properties:
* - `setup()`: An optional function run once before testing starts
* - `teardown()`: An option function run once after all tests are done
* - `preTest()`: An optional, async function run before a test
* - `postTest()`: An optional, async function run after a test is done
* - `structuredClone(obj, transferList)`: Required function that somehow
* structurally clones an object.
* Must return a promise.
* - `hasDocument`: When true, disables tests that require a document. True by default.
