If this issue only occurs in one browser, which browser is a problem?

Describe the Bug

When having a base option configured, the page prop resulting from having a dynamic route with paginated content doesn’t take that base into account.

This means that the URLs in page.url.prev and page.url.next are not prefixed with the configured base. This (strangely) doesn't cause issues in development mode, but when running a preview after build, the links don’t work correctly.

What's the expected result?

I believe page.url.prev and page.url.next should be correctly prefixed with base if it is defined in the configuration. If there are issues with that, the behaviour should at least be documented so developers can manually handle the case.

I think it makes sense to add the base by default, but if we change it now, I feel like it would break many existing setups. Documenting it might be a good solution for now, and we can revisit this in Astro 5.

I don't quite understand, what API is this in reference to? What is page.url.next? Can you link to docs on this API?

[bluwy]

It's https://docs.astro.build/en/reference/api-reference/#pageurlprev. Currently paginate() generates it, but it doesn't have knowledge of the current base IIUC.
