### Expected behavior

Normally when composing with notmuch and company, when you enter part of an e-mail address a list of suggestions will be shown from the notmuch-address functionality.

I would expect that corfu's completion would also provide a list of suggestions.

### Current behavior

In trying to use corfu and composing an e-mail, no suggestions come up from the notmuch-address functionality, only other completions like with dbabbrev.

### Steps to reproduce

Enable corfu as the completion, disabling company, since I believe they cannot co-exist according to the README in the module.

Attempt to compose an e-mail using notmuch and no suggestions are shown while entering addreses.
