Increasing a lock that is used by a job does not work

Example:
lock1 is defined with max_non_exclusive=0
job1 tries to get the lock non exclusive
Of course, it cannot get the lock. The task remains enqueued.
After updating the lock definition, the task still remains enqueued.
After removing the task from the queue, the job still cannot start. The job definition needs to be updated, before it can start.
