Attempting to Paste Behavior Tree Task with Decorators Pastes to Wrong Location

Attempting to paste a task that contains decorators does not paste it near the mouse location, and pastes it off screen instead.

Found in 4.11.2 binary. Reproduced in 4.12 Preview 4 binary and Main CL 2980216

1. Open the editor
2. Create a new behavior tree
3. Add Sequences and Selectors to make the tree take up a majority of the viewport
4. Add a Move To Task, and give it a couple of decorators
5. Copy the Move To Task (CTRL+C)
6. Scroll to the bottom node of the behavior tree
7. Paste the Move To Task (CTRL+V)

Result: The task is not pasted anywhere on the screen, and is instead offset either above or below the visible screen space.

Expected: The node would be pasted near the mouse cursor's location.
