How to handle the Guard dependency of parallel state?

[ODtian]

Suppose parallel state A and B, they recive "event_a" and "event_b" which both bind to a same godot action (like a click), if i only want to transit from B, how should I do？

In my real case, event_a is always called earlier than event_b, which make a StateIsActive guard on state A watching state B is useless, because transition guard of state A can't see whether B has changed because it always evaluate it before event_b send to B. Do we need some code to sync the state?

seems like not an issue of this addon, the solution is using _unhandled_input to ignore ui inputs which in my case event_a will not be triggered, godot docs has a good reference of how input event are handled in order.
