Steps to reproduce:
1. Open attached project "Tilemap.zip" and scene "SampleScene"
2. Open the Tile Palette window
3. In Project window, select Assets/Sprites/Potions/Pixel Potions Sprite Sheet.png
4. Expand and select the first three sprites from the sprite sheet.
5. Drag-and-drop the selected sprites into the Tile Palette window
6. When prompted with the "Generate tiles into folder" window, observe the folder path
7. Press the "Select Folder" button
8. Repeat steps 4-6. Note the difference in folder paths.
Expected results: Both multi-drag-and-drop operations prompt an asset to be saved in the same location (/Sprites/Potions)
Actual results: Subsequent multi-drag-and-drop operations prompt an asset to be saved in the parent folder (/Sprites), rather than the initial one (/Sprites/Potions)
