`協調世界時間` is actually coming from `COMPAT` provider, which is wrong. The
expected name `世界標準時間` in CLDR is in `zh-Hant` resource bundle which is not
available in `COMPAT` provider. Thus, comparing `zh-MO` and `zh-Hant` names
effectively asserts that the name is correctly coming from `CLDR` provider. I
confirmed that this regression test did fail with the runtime without the
proposed fix.
