*This effectively replaces PR 15465.* As outlined in https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map/forEach, the argument order when iterating through a `Map` is actually `value, key`. Ignoring the incorrect Array used in the old code, I cannot imagine that this would've worked anyway since we didn't use the actual `setTimeout`-functionRefs to clear the timeouts; please refer to the `setTimeout`/`setInterval` methods in the `SandboxSupportBase.createSandboxExternals` method.
