There was a problem hiding this comment.
This simulates the Safari behavior of trying to drain the queue until it's empty. So that we don't "fix" this by adding an infinite loop.
Proof:
<body>
<script>
let busy = true
const callback = () => {
if (busy) {
console.error('noo im busy')
queueMicrotask(callback)
} else {
console.log('im ok')
}
}
queueMicrotask(callback);
console.log("will add iframe");
const iframe = document.createElement("iframe");
iframe.src = "localhost";
document.body.appendChild(iframe);
console.log("did add iframe");
busy = false
</script>
</body>gets Safari infinitely stuck

Fixes #24458.
Just like #22459, this is caused by a Safari bug (https://bugs.webkit.org/show_bug.cgi?id=235322).
Our original solution for #22459 was #23111: if the microtask callback runs prematurely, we ignore it. This relied on the assumption that we always check for more work at the end of the task anyway. However, we don't check for more work if we aren't either rendering or committing — notably, we don't check for more work at the end of the event handler.
This fix is to allow the update to flush early. This doesn't respect batching but matches what Safari is trying to do (which is to flush everything early).
