Job expired in batches in the lastest Hangfire Pro

I recently upgraded to latest Hangfire (1.5.3) and Hangfire Pro.
In my batches (long running jobs) I now get a lot of jobs changing their status to “Job expired”. That wasn’t the case before.

Those jobs should not be flagged as expired, since the corresponding batched hasn’t even had time to start (it’s waiting on the results of previous long batches). Not sure it’s a bug or that has been done by design, but it’s a problem for me now. It looks more logical to start counting time after the batch starts.

As a workaround, how can I change the time it takes to get a job flagged as expired in batches ?
