Differentiation of icons is not visibly distinct of a prefab and variant when they have overrides. Refer the screenshots

Steps to reproduce:
1) Create a new project
2) In hierachy > Right Click > Create cube
3) Drag to project and make a prefab
4) Right Click > Create a prefab variant
5) Drag this variant as a child to original prefab in the hierarchy
6) Change the scale of both variant and prefab to (5,5,5)

Actual result: The addition override symbol appears on the prefab variant icon lines making it difficult to understand whether the gameObject is a prefab or a variant

Expected result: The addition override symbol does not hide the icon on the variant
