Noticing, as when Netscape topped around 80%, and then IE passed 80 on way to 95%, and now with Chrome: when a browser gets 80% market power, esp. with leading devtools so web devs live in it, content interop suffers. Not rationalizing or excusing; it is bad _per se_. Real, too.

Cc: @bz_moz @davidbaron who probably know at a glance what's up.

var f = document.createElement('iframe') var loaded = false; var t = ""; f.addEventListener('load', () => { loaded = true; }) t += `${loaded},`; document.body.appendChild(f) t += `${loaded},`; setTimeout(() => { t += `${loaded}`; console.log(t); }, 100);
