Restore on mouse leave based on conditions

I have 5 pictures, in a drag drop slide. 

Start: On mouse hover they grow large (state). and restore to normal after mouse leave. Perfect => Restore on mouse leave=ON

Dropped: When dropped they restore to normal after mouse leave. Wrong.
I would like them to stay large. Restore on mouse leave=OFF

I have tried 2 triggers one with Restore on mouse leave=ON, and another on
Restore on mouse leave=OFF based on a condition. However the condition is completely ignored.

What other options do I have?

Start:          Small > Large > Small
Dropped:   Small > Large > Large

Thanks in advance for your support.
