Steps to Reproduce
- Create a regular Mat Func, a Material, and a MIC from that Material.
- Add the Mat Func into the Material and save all three assets.
- Check the reference viewer on the Mat Func with referencer depth set to 2, confirming that it shows the Mat and then the MIC
- Delete the Mat Func from the Material and save the Material.
- Check the reference viewer on the Mat Func with referencer depth set to 1, note how it is showing the MIC as a direct referencer when it is not and never was.
