Rule chaining not working with Promise.all

Comienza reproduciendo el ejemplo de Promise.all del issue y, a continuación, inspecciona Engine.run y el manejo de runtime-fact utilizado por almanac.addRuntimeFact. Se considera terminado cuando las ejecuciones paralelas producen los resultados y eventos correspondientes para samuel, joseph y anthony, coincidiendo con el comportamiento secuencial.

If I run the engine sequentially, I am getting the desired result. If I run it in parallel, I am getting results only for the first run.

Output

Running sequentially

loading student information...
loading student information for "samuel"
samuel CANNOT NOT have Physics as favorite subject as they do not study Mathematics
loading student information...
loading student information for "joseph"
joseph DOES NOT have Physics as favorite subject
loading student information...
loading student information for "anthony"
anthony HAS Physics as their favorite subject

Running parallelly (Promise.all)

loading student information...

loading student information for "samuel"
loading student information for "joseph"
loading student information for "anthony"
samuel CANNOT NOT have Physics as favorite subject as they do not study Mathematics
