Laravel url helper returns incorrect root url in wp-admin (affects Livewire v4.0 scripts)

[kevinlisota]

Version

v5.0.5

What did you expect to happen?

When using Livewire on some pages I created inside of wp-admin, the @livewireScripts command outputs a script URL that references the routes generated by Livewire. The output of @livewireScripts should result in a URL like https://mydomain.com/livewire/livewire.min.js.

What actually happens?

In the new version of Livewire v4, they are now using the Laravel url() helper to generate URLs. In v3, they used a root-relative path. Inside of wp-admin, the Laravel url() function returns https://mydomain.com/wp-admin/admin.php, which is the page URL I'm using, not the root URL. I briefly tested the front end, and url() appears to work correctly there, so likely something related to wp-admin. Here is a link to the discussion on the Livewire repo.

The result is that @livewireScripts renders URLs (and update URLs) that don't match the Livewire routes. Instead of https://mydomain.com/livewire/, we get https://mydomain.com/wp-admin/admin.php/livewire/.

Steps to reproduce

1. Install Livewire v4
2. Render @livewirescripts inside of wp-admin, either in the footer or in a template.
3. Compare the rendered URLs to the Laravel route table and note the mismatch.
