Unexpected 404s When Loading Remote Modules from different origins

[MatejFacko]

When using @module-federation/runtime to dynamically load remote modules via registerRemotes and loadRemote, I encounter multiple 404 network requests when the remote app is hosted on a different origin .

Despite the 404s, the correct module eventually loads. However, the excessive failed requests may impact performance and mislead monitoring tools.

Expected Behavior

Only the correct absolute URL for the remoteEntry.js and other JS chunks should be requested, without extra or fallback 404s.

Actual Behavior
1. Running locally app where call registerRemotes([{ name: 'RemoteApp', entry: 'https://remote.origin/remoteEntry.js', type: 'module' }]).
2. I then call loadRemote('RemoteApp/Bootstrap', { from: 'runtime' }).
3. Multiple 404s occur before the correct resource is loaded

This only happens when entry points to a different origin.
