Nova.booting(function (app) {}) receives undefined sometimes

[hivokas]

• Laravel Version: 11.36.1
• Nova Version: 5.0.5

Description:

I have a custom script where I register a few components.

Here is what I have in NovaServiceProvider:

Nova::serving(function () {
    Nova::remoteScript(mix('js/nova.js'));
});

Here is what I have in the script:

Nova.booting(function (app) {
  app.component('HtmlContentModal', HtmlContentModal);
});

Sometimes app is undefined (not always) which triggers an error.

Safari Version 18.1.1:

Chrome 131.0.6778.205:

As a result, I just get a gray screen instead of a desired page.

Feels like some kind of race condition.

Detailed steps to reproduce the issue on a fresh Nova installation:

1. Create a script which registers a component.
2. Register compiled script in service provider.
3. Open any page in Nova and try to reload it many times. Sometimes you'll be getting this error.

Thanks for fixing @crynobone! Is the fix going to be part of 5.0.6 release?
