Describe the issue

You can delete the small scenery ghost by right-clicking on them.

When placing any type of object, you see a white ghostly representation of the object you're placing. Normally you would not be able to destroy this, as the object is automatically removed when you move the cursor, or close the building menu.
See wall pieces, large scenery, or rides for reference.

Steps to reproduce

1. Select a small scenery object in the scenery window
2. Hover over a tile, but don't place the object
3. Right click on the white ghost version of the object
4. The scenery object is destroyed
