/**
 * v2.14.6 regression: with only one inline spec offered by the framework
 * (common on 2FA-only pages after username/password submit), the picker
 * spec and OTP spec would both target specs[0] and the picker dataset,
 * being added last, would clobber the OTP chip inline. The picker now
 * falls back to the system menu in the single-spec case so the OTP chip
 * keeps the only inline slot.
