Favicon missing when deploying NextJS app to Firebase Hosting

[nicklbaert]

We have a NextJS app containing a favicon under public/favicon.ico. This favicon is not displayed correctly when using the deploy action.

We use the following CD workflow:

When doing this, the favicon of the webpage does not show up.

This does not happen when performing the exact steps from the workflow manually and using firebase deploy --project dev.

Any help is highly appreciated!
