Not receiving activesupport notifications under 1.3.1

[iftheshoefritz]

We upgraded from 1.1.2 to 1.3.1 and found that we no longer get activesupport notifications with this line in an initializer:

ActiveSupport::Notifications.subscribe("feature_operation.flipper") do
   # block was being called in 1.1.2 but not in 1.3.1
end

What might have changed?

EDIT: I wrote this with the assumption that this was in a failing test, but if this is while running in dev/test/prod then that's completely different

It's probably because of test_help.rb in https://github.com/flippercloud/flipper/blob/main/lib/flipper/test_help.rb.

It doesn't pass any options for the instrumenter (usually active support notifications by default if you're using rails) to the flipper initialize method and it defaults to a "noop" instrumenter over here https://github.com/flippercloud/flipper/blob/main/lib/flipper/dsl.rb, which I believe doesn't do anything?

It would be nice if it was possible to have it respect the instrumenter in the test help
