Losing context when using cats parallel

[igullickson]

Hello, we observed an issue where context is lost after a call to a cats parallel method is made, such as parSequence.

Here is an example test that demonstrates the issue: https://gist.github.com/igullickson/2c45e5922c464d196f6b4a2aa10c500a

We are using:

• cats 2.8.0
• cats effect 2.5.5
• kamon 2.5.8
• kanela-agent 1.0.14

We are using the following configuration for kamon/cats effect:

kanela.modules {
  executor-service-capture-on-submit.enabled = true

  executor-service {
    within += "cats.effect.internals.Callback\\$AsyncIdempotentCallback"
  }
}

Trying other configuration variations such as the example here did not fix the context propagation.

Any help or feedback otherwise is much appreciated.

Hey @igullickson, thanks for reporting this and more importantly, for the reproducible! I'm not sure how easy it would be to get this fixed, but I'll take a look at it asap. Adding this to my work queue.
