Why does TaskCancelation error is not bubbling to application route?

[ollar]

I just need to quiet these exceptions somehow to avoid those numerous try-catches all over the project. I am trying to proceed them in application's error action but it does not catch any 😄 I am using await taskInstance.perform() constructions, and I can't change this behavior sometimes.
(yes, I've read the docs on "https://ef4.github.io/ember-concurrency/docs/task-cancelation-help")
Can someone suggest any solution please?
