HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

/*your preparation JavaScript code goes here
To execute async code during the script preparation, wrap it as function globalMeasureThatScriptPrepareFunction, example:*/
async function globalMeasureThatScriptPrepareFunction() {
    // This function is optional, feel free to remove it.
    // await someThing();
}

Tests:

actual
(function() { var loadTimeout = 5000; var loadFired = false; var timeoutFallback; function onWindowLoad() { if (!loadFired) { loadFired = true; clearTimeout(timeoutFallback); window.dataLayer = window.dataLayer || []; window.dataLayer.push({ 'event': 'window_load' }); } } function fallback() { if (!loadFired) { loadFired = true; window.dataLayer = window.dataLayer || []; window.dataLayer.push({ 'event': 'load_fallback' }); } } window.addEventListener('load', onWindowLoad); timeoutFallback = setTimeout(fallback, loadTimeout); })();
future
(function() { var loadTimeout = 5000; var loadFired = false; var timeoutFallback; function onWindowLoad() { if (loadFired) { return; } loadFired = true; clearTimeout(timeoutFallback); window.dataLayer = window.dataLayer || []; window.dataLayer.push({ 'event': 'window_load' }); } function fallback() { if (loadFired) { return; } loadFired = true; window.dataLayer = window.dataLayer || []; window.dataLayer.push({ 'event': 'load_fallback' }); } window.addEventListener('load', onWindowLoad); timeoutFallback = setTimeout(fallback, loadTimeout); })();
