Space loads defined at the SpaceType level do not get assigned schedules from Default Schedule Sets assigned at the Space level

Issue overview

In my model, I have (for example) two Break Rooms with different operating schedules. I would like to define both as a single 'Break Room' space type, and inherit loads associated with that type, but with different schedules applied. So I:

1. Created a Space Type with Loads, but no Default Schedule Set
2. Created multiple Default Schedule Sets, and applied them at the Space level to different spaces

The spaces inherit loads+load defs from the SpaceType, but the Schedules defined in the Default Schedule Set applied at the Space level are not assigned to those loads.

Expected Behavior

From the inheritance diagram I expected schedules assigned at the Space level to be applied to the loads, no matter from which level they are inherited.

The setup above will produce a severe error Missing required property 'schedule_name' for the inherited loads.

Possible Solution

Allow schedules inherited from 'lower' levels to apply to loads inherited from 'higher' levels?

@DavidGoldwasser is this expected behavior?

Environment

Some additional details about your environment for this issue (if relevant):

• Platform (Operating system, version): Windows 11
• Version of OpenStudio (if using an intermediate build, include SHA): OS 3.6.0

Reproduce the issue in OpenStudio 3.6.0 using a Space Type with loads and multiple Space-level Default Schedule Sets, as described. Trace the inheritance handling for loads and schedules; done means each inherited load receives the schedule from its Space-level Default Schedule Set without a severe missing schedule_name error.
