There was a problem hiding this comment.
nit: this comment would be better next to a test case, IMO
Currently, there's no check if the task (that is being canceled) has the right state. Only `scheduled` and `running` tasks can be canceled. If the task has a non-appropriate state, then an error will be thrown. Cancelation should not throw an error on an already canceled task, e.g. `clearTimeout` does not throw errors when it's called multiple times on the same timer. PR Close angular#45711
