Unclear if this is a bug or feature.

As far as I can tell, the addition of an empty option is intended. See https://searchfox.org/mozilla-central/source/browser/extensions/formautofill/content/autofillEditForms.js#403, https://searchfox.org/mozilla-central/source/browser/extensions/formautofill/content/autofillEditForms.js#427 or https://searchfox.org/mozilla-central/source/browser/extensions/formautofill/content/autofillEditForms.js#449

Every select box features an empty option which is always listed as the first item. It's only possible to save or updated the form when all options are not empty.
