Bug or feature? skip_on_upstream_skip=False does not respect flow branches.

[gryBox]

Hi - Below is an example of a flow where one of the branches has a task with skip_on_upstream_skip=False and the trigger any_successful. As the diagram shows both branches of the flow are called.

One way to get around this is to use the trigger not_all_skipped. However is there a legitimate use case for a trigger handling results the results in it's own branch?

Code

import prefect
from prefect import Flow, task, apply_map, Parameter, unmapped
from prefect.tasks.control_flow import ifelse

import random


@task
def list_maker(input_num):
  print(input_num)
  lst = [random.randint(1, 10) for i in range(input_num)]
  print(lst)
  return lst
  
@task(
  trigger=prefect.triggers.any_successful,
  skip_on_upstream_skip=False
)
def expensive_func(num_from_input):
  return 5*num_from_input

@task
def is_even(input_num):
  return (input_num % 2) == 0

@task
def odd_num(input_num):
  raise Exception()
  return 10*input_num



with Flow("map the map") as flow1:
  input_num = Parameter("input_num", default=3)

  random_list = list_maker(input_num)
  odd_res = odd_num(input_num)

  ifelse(
    is_even(input_num),
    random_list,
    odd_res
  )

  expensive_res = expensive_func.map(random_list)

flow1.visualize()
    state = flow1.run(
      parameters=dict(input_num=3)
    )
    flow1.visualize(flow_state=state)
