[BUG] - OneTimeJob Missing Execution

[gaoyaxuan]

Describe the bug

It is not executing according to LimitModeWait mode, but rather behaving like LimitModeReschedule.

To Reproduce

Steps to reproduce the behavior:

func main() {
	s, _ := gocron.NewScheduler(gocron.WithLimitConcurrentJobs(10, gocron.LimitModeWait))
	s.Start()
	fmt.Println("begin", time.Now().Format("2006-01-02 15:04:05"))
	_, _ = s.NewJob(
		gocron.OneTimeJob(gocron.OneTimeJobStartDateTimes(time.Now().Add(3*time.Second), time.Now().Add(6*time.Second), time.Now().Add(15*time.Second))),
		gocron.NewTask(
			func() error {
				fmt.Println("Run time:", time.Now().Format("2006-01-02 15:04:05"))
				time.Sleep(10 * time.Second)
				return nil
			},
		),
		gocron.WithSingletonMode(gocron.LimitModeWait),
	)

	select {
	case <-time.After(15 * time.Minute):
	}

}

Execution Results:

begin 2024-09-07 15:26:27
Run time: 2024-09-07 15:26:30
Run time: 2024-09-07 15:26:42

time.Now().Add(6*time.Second) not running
If you delete gocron.WithLimitConcurrentJobs(10, gocron.LimitModeWait) or set gocron.WithLimitConcurrentJobs(1, gocron.LimitModeWait) , job all will run
