I have an app that has an iframe within. There's a redux instance on the top frame and another instance (different app) inside the iframe. The tools have the instance switcher dropdown which shows 3 values: "autoselect instance", "instance 1" and "instance 2".

No matter what's selected on the instance switcher, when ever an action happens on the top frame instance (i.e. instance 1), the tools go back to showing/selecting that instance — even when the action occurs on the instance 2.

It doesn't switch to instance 2 from instance one ever, only from 2 to 1 for all events.

It gets very disruptive when you're trying to debug on instance 2. It feels a lot like a bug.
