1. Open new scene
2. Create multiple objects in the scene
3. Make one of them not pickable from the hierarchy (hand icon on the left of the object)
4. Select objects in the scene and perform a CTRL+I shortcut to inverse the selection

Result
The non-pickable object(s) will get selected
Expected
the pickable property should prevent the object(s) to be selected

NOTE
CTRL+A already does it and was fixed in 2020.2.0b3 as part of this defect -> https://fogbugz.unity3d.com/f/cases/1250345/
