Reproduction steps:

# Open the attached project
# Open the Tile Palette (Window > 2D > Tile Palette)
# Select the “Floor Grid” GameObject in the Hierarchy window (Board > Grid - Floor > Floor Grid)
# Select a Tile in the Tile Palette and place it in the Scene View
# Switch to “GameObject Brush” in the Tile Palette
# Place the Tile in the same place where the previous Tile was placed
# 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)
