[URP] Editor performance is heavily impacted when changing Renderer Feature's values in the Forward Renderer

Package: Scriptable Render Pipeline Universal

-

How to reproduce:
1. Create a new project with the URP template
2. In the Project Window, select the "ForwardRenderer" Asset (Assets->Settings)
3. In the Inspector, click the "Add Renderer Feature" button
4. Select "Screen Space Ambient Occlusion"
5. Move the sliders around

Expected result: Performance is not heavily impacted
Actual result: Performance is heavily impacted

Reproducible with: 2020.2.0a20, 2020.2.0b4 (10.0.0.preview.26)
Couldn't test with 2018.4.27f1, 2019.4.11f1, 2020.1.6f1, 2020.2.0a19 (Required package version is not available)
Couldn't test with Packages lower than 10.0.0-preview.26 (SSAO Renderer Feature is not available in the Forward Renderer )

  1. This is a duplicate of issue #1279804

    A short freeze occurs in the Editor when expanding or collapsing with the arrow the Renderer Feature in the Forward Renderer

  1. Resolution Note:

    The proper fix for this bug is to move away from subassets and implement polymorphic serialization. However PolymorphicSerialization has some issues that prevent us to use it. Postponing the bug marking the issue to be reopened when the dependent serialization issue is fixed.
