How to reproduce:
1. Open the attached “IN-106882” project
2. Open the “SampleScene”
3. Enter Play mode
4. Expand the objects in the following order: “Root” > “Group 0” > “Subgroup 0.0”
5. Double click any of the “Item” objects
6. Move the cursor to the bottom, then top of the Game view
7. Observe the result

Expected result: The drag and drop preview does not follow the mouse
Actual result: The drag and drop preview follows the mouse

Reproducible with: 2023.3.0b4, 6000.0.53f1, 6000.1.11f1, 6000.2.0b9, 6000.3.0a1
Could not test with: 2021.3.51f1, 2022.3.64f1 (MultiColumnTreeView not supported), 2023.3.0b3 (Could not solve modal not appearing)

Reproduced on: Windows 11
Not reproduced on: No other environment tested

Workaround: Create a variable to track if the modal is open. If it’s open, return false in the canStartDrag callback

Notes:
- Reproducible in Player
- If the cursor is moved outside of the Game view during Play mode, a “NullReferenceException: Object reference not set to an instance of an object” error occurs and Play mode must be re-entered to reproduce the issue
