Issue with 'Back' button navigation within the application

[sgabler]

Hello,

this project is really cool. I played around with it locally and find it very useful!

It seems that back navigation is either not working, or is not implemented yet.

Here are the steps to reproduce the issue:

1. Navigate to page A within the app, e.g. "search results for 'fight'"
2. Navigate to page B within the app, e.g. "title page for 'Fight Club'"
3. Click on the 'Back' button on the browser.

Expected behavior:
The application navigates back to page A within the Svelte app.

Actual behavior:
The application navigates back to the most recently visited page prior to visiting the Svelte app.

Thank you so much for your time and consideration
