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

Firefox, Safari

Describe the Bug

According to the docs, Astro prefetch should work on any browser whether or not View Transitions are enabled (as it is not mentioned otherwise).

I virtually tried any combination under my astro.config.mjs: prefetch: true, prefetch.prefetchAll: true, etc. And also to manually append the data-astro-prefetch attribute as explained in the docs and enable/disable ViewTransitions.

Under the "Network" tab of both Firefox 124 (latest) and Safari 17.4 (latest) there is no way I can see the incoming documents.

The only way to see them in that tab is to manually call prefetch() in a script tag using { with: 'fetch' }, however, those pages are then requested again to the server once I click on the correspondent links.

On Chrome and Edge (and I suppose any other Chromium-based browser) everything works as per docs.

I am not sure if this expected, if it's a bug or if I (hopefully) misinterpreted the docs and actually doing something wrong. Thank you.

What's the expected result?

To work on Firefox and Safari as it works on Chrome.
