Scaling grid thumbnails beyond 100% proportionally works... sometimes?!

Hi! I’m trying to get the thumbnails of a grid made up of multiple collection wrappers pointing to the same list to resize proportionally BEYOND 100%. All thumbnails are the same size. As I resize the window one thumbnail behaves as I want (no 6 from the top). And another one only scales up to 100% and then stops (no 13 from the top). Both instances have the same class and properties but behaves differently.

What am i doing wrong?

Thanks for any help!
