This PR has a test case demonstrates the error in the current master, and a less-than-elegant, but non-invasive way to avoid the error of conflicting action and option listeners without negatively impacting either. I am open to better solutions, but other than establishing a separate emitter for both options and actions, I don't know a better way than a naming convention (
action_
prefix) to keep them from colliding, in my brief inspection anyway.
