Help me to understand how preventDefault should work properly in case of "vire:preloadError"

[albodev]

Hey there

I can't figure out how the interrupt event should work inside the preload error handler in vite

function handlePreloadError(err: Error) {
    const e = new Event('vite:preloadError', {
      cancelable: true,
    }) as VitePreloadErrorEvent
    e.payload = err
    window.dispatchEvent(e)
    if (!e.defaultPrevented) {
      throw err
    }
  }

We have dispatched event that we are going to prevent in our handler. But we have synchronious part of code with if condition, that (if I get it right) should be executed earlier

So how it should properly prevent our code to thrown an error if this event will be executed after synchronious code as macrotask?

I had this question cause I can't handle preload error without error was thrown in my app

Thank you for answers!
