The 'type' selects the test logic to run. Most message type11// handlers use postMessage() to respond to the sender with test results.12// The sender then validates the test results after receiving the response.13//14// Both |target| and |target_origin| are optional. |target| is used15// to send message responses back to the sender. When omitted, the16// 'source' from received MessageEvents is used instead.17//18// For window messaging, |target_origin| specifies the origin to receive19// responses. Most window tests use '*' for the |target_origin|. Worker20// and message port tests must use undefined for |target_origin| to avoid21// exceptions.22function add_message_event_handlers(receiver, target, target_origin) {23  receiver.addEventListener('message', async function (message_event) {24    const message_data = message_event.data;25    // Reply to the sender using the 'source' from the received MessageEvent.26    let message_source = message_event.source;27    if (message_source === null) {28      // However, some message senders, like DedicatedWorkers, don't include29      // a source.
