Steps to reproduce:
# Create a new URP project
# Create a Renderer Feature (Assets>Create>Rendering>URP Renderer Feature)
# Add this Renderer Feature to any URP Renderer Data asset
# Either delete the Renderer Feature or comment its code out in the script file
# Inspect the URP Renderer Data asset to find that the Feature is now missing
# 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
