Scroll preservation persists globally after visiting a page with data-turbo-action="advance"

[Jamie-Vandenbalck]

Description:

When navigating to a page (e.g., the blog index) that uses data-turbo-action="advance", Turbo starts preserving scroll positions globally for all subsequent navigations, even on pages that do not use data-turbo-action="advance". The issue only occurs after visiting the page with this attribute—if the page is never visited, scroll behavior works as expected.

Steps to Reproduce:

1. Add data-turbo-action="advance" to a link on the blog index page (/blog):

<turbo-frame id="blog_posts" src="{{ path('app.blog.index', routeParams) }}"data-turbo-action="advance">

2. Visit the /blog page.
3. Navigate to an unrelated page (e.g., /about) using a standard Turbo-enabled link: <a href="/about">About</a>
4. Observe that the scroll position on the /about page is preserved from the /blog page, even though data-turbo-action="advance" is not used on the /about page.

Expected Behavior:

Scroll preservation should only apply:

• Within the context of the /blog page where data-turbo-action="advance" is explicitly used.
• Scroll position should reset appropriately when navigating to unrelated pages (e.g., /about).

Actual Behavior:

• After visiting the /blog page and using data-turbo-action="advance", Turbo globally preserves scroll positions across all subsequent pages.
• This behavior persists for unrelated pages (e.g., /about), even if they do not use data-turbo-action="advance".
• If the /blog page is not visited, scroll behavior works as expected, resetting to the top for each new page.

Environment:

Turbo Version: 8.0.11
Browser: Safari 18.1.1, Chrome 131
Operating System: macOS 15.1.1

Yea. I see the same with data-turbo-action="replace"
