Reproduction steps:

1. Open the attached project
2. Open the Tile Palette (Window > 2D > Tile Palette)
3. Select the “Floor Grid” GameObject in the Hierarchy window (Board > Grid - Floor > Floor Grid)
4. Select a Tile in the Tile Palette and place it in the Scene View
5. Switch to “GameObject Brush” in the Tile Palette
6. Place the Tile in the same place where the previous Tile was placed
7. Observe the Tiles in the Scene view

Expected result: Both Tiles are in the same place
Actual result: There’s an offset between the Tile that was placed with the “GameObject Brush” and the one placed with “Default Brush”

Reproducible with: 2021.3.10f1, 2022.1.17f1, 2022.2.0b8, 2023.1.0a11
Couldn’t test with: 2020.3.39f1 (couldn’t downgrade, “GameObject Brush” not present)

Reproducible on: Windows 10 (21H2)

Note: The offset is proportional to the Cell Gap value set on the Grid Component (“Grid - Floor” GameObject)
