Extended Properties on Perspective are not serialized / saved to folder

[OlavRab]

Describe the bug
Extended properties on perspectives are not being serialized in the database.json file!

To Reproduce
Steps to reproduce the behavior:

1. Create a model (I have a compatibility level 1567 model)

2. Add a couple of tables from a powerquery source

3. Add a perspective, make a couple of tables visible in the perspective

4. Add an extended property to the perspective
   

5. Save the model to a folder with the following serialization settings:
   

Expected behavior
Normally, I would expect the ExtendedProperty and its value to be serialized into the database.json file as part of the TabularEditor_Perspectives Property. Once I re-open the model, the Property that I added, should be visible once again.

Observed Behavior
What actually happens is that the property doesn't get picked up and saved/serialized at all (note the screenshot from the database.json file). As you can see, Annotations added to the perspective are saved.

Once I re-open the model after saving it to folder, the ExtendedProperty is gone, the annotation is still there

Application specifics

• Tabular Editor 2.X version: [e.g. 2.21.1]
• Semantic Engine used: PowerBI Premium per User
• Model Compatibility Level:1567
