Steps to reproduce:

1. Create a new URP project
2. Create a Renderer Feature (Assets>Create>Rendering>URP Renderer Feature)
3. Add this Renderer Feature to any URP Renderer Data asset
4. Either delete the Renderer Feature or comment its code out in the script file
5. Inspect the URP Renderer Data asset to find that the Feature is now missing
6. Try clicking on the three dots on the missing Renderer Feature item

Expected result: a popup with options to Move Up, Move Down and Remove should be displayed

Actual result: an error is thrown and the popup does not open
