Areas and Proximity Triggers in 2024

I successfully created Runway Entry Lights in 2020, which turn on if any object is inside the area placed over the runway, or an aircraft is inside the approach corridor.

This works exactly as planned. However, moving to 2024, SU-4 the Worldscript fails to detect the presence of Anything inside the areas. Examining the airport using Debug Worldscript, I see that Asobo now have an area marked out over each runway. Is this killing user created Proximity Triggers, or is it setting a SimVar we can access?
