When using multiple jsbin embeds in a presentation, each bin doesn't load until I click one of the headers (ie, "HTML", "CSS", etc.). This only seems to happen in larger presentations like this one (navigate to /3/4 from the start to see the unloaded embed). I tried running the code mentioned here without success:
[].forEach.call(document.querySelectorAll('iframe'), function (iframe) {
try {
iframe.contentWindow.postMessage('jsbin:refresh', '*');
}
catch(err){
}
});
