Parallel delays cause last delay to keep running indefinitely

[PhilippFr]

Description

When having two parallels paths of 2 delay and a WaitAll Join, one of the delays gets stuck and never finishes.

Steps to Reproduce

Two paths of each two delay with different short timings (1, 2, 3 and 4 seconds in my case). Joined by a WaitAll Join.

parallel-delay-bug.json

Expected Behavior

I expect both path to complete after the set time and join at the WaitAll join.

Actual Behavior

The last Delays stays "running" indefinitely, past its set time of e.g. 4 seconds.

I just happened to launched the Elsa Designer with the latest 3.5.2 release. I was interested in this since I did some work with scheduling workflow flowchart activities and wondered if it was related. I tried manually to reproduce this issue and I was not able to. I then imported the parallel-delay-bug.json and was still not able to reproduce. The only difference between my environment and yours is that I am using Chrome, not Edge. But I can't imagine could be a significant difference. I hope that someone else is able to help you with your issue!

Which scheduler provider is being used? The default one, Quartz.NET or hangfire?
