Memory Increase with mouse over Content Browser with AnimBP visible

Memory Increase with mouse over Content Browser with AnimBP visible

1. Create a Third Person template project
2. Go to Editor Peferences>General>Miscellaneous and enable Show Frame Rate and Memory
3. Open the Content/Mannequin/Animations folder in the content browser
4. Note the activity of the Memory stat at the top of the editor
5. Open ThirdPerson_AnimBP, then close it
6. Move the mouse over the Content Browser and hold it there for about 20-30 seconds
7. Note the activity of the Memory stat during that time (should be rapidly increasing)
8. Move the mouse off of the Content Browser entirely and note the Memory activity

Result: Memory increases when the AnimBP is visible in the Content Browser and the mouse is over the CB. Selecting a different folder will cause it to stop.
Expected: No memory increase
