Optional aria

  • "1.0" will enable some regressions to support the 1.0 spec.

Optional autocomplete

autocomplete: string

Sets the autocomplete= attribute of the input element. Setting this attribute aims to prevent some browsers (particularly Chrome) from providing a clashing autofill overlay.

The best practice for this attribute breaks over time (see https://stackoverflow.com/questions/15738259/disabling-chrome-autofill) and is specific to different forms. If you are observing chrome's autofill clashing on your form, update this attribute to the best practice du jour.
