// rather than h23 (00:00 - 23:59). Same can happen with hour12: true in French, which Chrome resolves to h11 (00:00 - 11:59)
// rather than h12 (12:00 - 11:59).
// - WebKit returns an incorrect hourCycle resolved option in the French locale due to incorrect parsing of 'h' literal
// in the resolved pattern. It also formats incorrectly when specifying the hourCycle option for the same reason. [3]
