The base-class abbreviation() falls back to its displayName() which starts by asking for data() for the relevant time. Unfortunately the backend's data() was delegating (if ICU version is too old, or the transition lookup failed) to abbreviation for one field of that. So short-cut out to how the backend's displayName() gets abbreviations (and how the look-up of transitions finds their abbreviations).
