Using "Watch This Value" on Pawn causes memory leak

Reproduced 3/3 times, issue also occurs in //UE5/Release-5.0 - CL 20979098 Binary. Confirmed NOT a Regression.

No memory leak occurs when watching a new blank Actor BP, which implies the root cause is from the Pawn BP.

1. Create and add a Pawn BP to a level
2. Open Level BP
3. Wire a BeginPlay node to a GetActorByClass node
4. Set Actor Class to your Pawn
5. Right-click the return value and select "Watch this Value"
6. Set the debug object to your level
7. PIE
8. Open Task Manager

Actual Result: You can see a gradual memory leak coming from the editor. On more complicated pawns (including new blank Character BPs) the leak is even faster.

Expected Result: No Memory Leak
