Task concurrency not being respected

[empz]

Steps to reproduce:
List the minimal actions needed to reproduce the behavior.

1. Create a task that takes longer than its "every" property
2. Set the concurrency to 1

option task = {name: "Downsample raw data", every: 10s, offset: 10s, concurrency: 1}

Expected behavior:
I'd expect only one task to be started at a time.

Actual behavior:
Multiple tasks are started and running at the same time. Concurrency option is not being respected.

Environment info:

• System info: Windows 10 Enterprise LTSC 2019
• InfluxDB version:
  InfluxDB v2.3.0+SNAPSHOT.090f681737
  Server: 090f681
  Frontend: a2bd1f3

Update
I've tried creating a task via Influx CLI also. Same thing.
