Mutating a component with insert(_one) doesn't trigger Mutated query filter #333
Description
Expected Behavior
I tried to make a small example and it should print "Tag added" once because the system with Added filter should be called once.
Or maybe I'm wrong and there is another way to add a component to an entity.
Actual Behavior
"Tag added" is never printed meaning the print_added function is never called.
Steps to Reproduce the Problem
- Write a system inserting a component into an entity with insert_one or insert
- Write a system using one of the three filter with the previous component
- This system will not work as intented
