1. Notify User: Instead of canceling, a new fetch status called "delayed" is set if the request takes too long. This status is used to render a message to the user.

2. Add Cancel Button: A cancel button is added that allows the user to manually cancel the request if they wish.

3. Abort on Cancel: When the cancel button is clicked, the request is aborted using the AbortController.
