description: Fallback value for overflow option

    sec-getoption step 3:

      3. If _value_ is *undefined*, return _fallback_.

    sec-temporal-totemporaloverflow step 1:

      1. Return ? GetOption(_normalizedOptions_, *"overflow"*, « String », « *"constrain"*, *"reject"* », *"constrain"*).

    sec-temporal.plaintime.from step 2:

      2. Let _overflow_ be ? ToTemporalOverflow(_options_).
