Asynchronous Image Loading from Disk Documentation leads to memory leak

The documentation example to create your own asynchronous image load from disk results in a memory leak that is noticeable using the task manager. 

1. Open a project in 4.22, 4.23 or 4.24

2. Follow the documentation for Asynchronous Image Loading: [Link Removed]

3. When finished, open up a task manager window. 

4. Load and clear the image while watching your memory in task manager. (continue to clear/load until you see changes) 

Result: Memory Leak results after completing the documentation step by step and trying to load an image from disk

Expected: Image to load and be cleared upon clearing image
