What are the factors that affect the transition from Elements Activated to Elements Completed by zeebe, and what is the main issue that took nearly seven seconds to complete?

version:8.1.0
**Describe the bug**
Sometimes jobs are activated exactly 10 seconds after th… e corresponding service task is activated. In general this can happen for various reasons, for example connection issue between worker, gateway and broker. 10 seconds is also the default request timeout for clients.
We've recently started to observe this in our QA runs, where these delays cause test failures. Since the network should be in a stable condition and this has only recently become an issue, it seems likely that this is actually a regression that we need to fix.
**To Reproduce**
With a current snapshot version of Zeebe and a spring-zeebe `8.0.5` this was at least not trivially reproducible.
**Expected behavior**
Under stable network conditions and barring any other issues, there should be virtually no delay between service task activation and job activation.
