How can I get mutt/neomutt to not close an empty edit field when backspace is pressed?

I used [mutt-wizard](https://github.com/LukeSmithxyz/mutt-wizard) to configure neomutt. When I edit e.g. the from-address by pressing f in the Compose view (just before sending my mail) it let's me edit the field. The command line becomes an edit line, this is below the status line. If I delete the address completely by pressing backspace, it closes the edit line and leaves the address unchanged, if I want to delete more characters than there are. This happens easily and is mildly annoying. I guess backspace is bount to close the edit operation/leave/unselect the field? I would like to enter a new address after I deleted the old one and pressed backspace more than once.
