allauth sets placeholder="Code" on the field. Grey text sitting inside the otp
boxes reads as an already-typed code, so it goes -- the sr-only label outside the
box still names the field.
Suppressed with placeholder=False rather than by deleting the key: as_widget()
merges the widget's own attrs back in at render time, so popping it from a copy
does nothing. Django's attribute template omits attrs whose value is False.
