description: Verify the result of calendar.fields() is treated correctly.

info: |
|

sec-temporal.plainyearmonth.compare steps 1–2:
|
||
1. Set _one_ to ? ToTemporalYearMonth(_one_).
|
||
2. Set _two_ to ? ToTemporalYearMonth(_two_).
|
||
sec-temporal-totemporalyearmonth step 2.c:
|
||
c. Let _fieldNames_ be ? CalendarFields(_calendar_, « *"day"*, *"month"*, *"monthCode"*, *"year"* »).
|
||
sec-temporal-calendarfields step 4:
|
||
4. Let _result_ be ? IterableToList(_fieldsArray_).
