I am creating a cup and a plate in blender 2.8, and I have such an issue. While I'm grabbing a face of a vertex of the plate it immediately attaches to the closest part of the cup from my vewpoint. The same happens when I'm moving the whole olate in Edit Mode. While being in Object mode, those two objects move together, although I triend to Unparent them and to separate from relation. I tried to demonstrate the issue below, thank you for help in advance!
