[2.x] Hash duplication on page refresh when using http instead of https

[ramonmalcolm10]

Versions:

• inertiajs/inertia-laravel version: 2.x-dev
• @inertiajs/react version: 2.0.0-beta.3

Describe the problem:

When using Inertia JS with URLs served over http (e.g., during local development), refreshing the page causes the hash in the URL to duplicate. For example, navigating to http://localhost:8000/#pricing and refreshing the page results in the URL changing to http://localhost:8000/#pricing#pricing.

This issue does not seem to occur when using https.

Steps to reproduce:

1. Set up an Inertia.js project.
2. Serve the application over http (e.g., http://localhost:8000).
3. Navigate to a URL containing a hash, such as http://localhost:8000/#pricing.
4. Refresh the page.
5. Observe the URL.
