Thanks, this helped me find a bug. I thought my masonry code didn't work because Firefox poor support for "break-inside: avoid;", so I was surprised to see your Pen work just fine. After investigating my code, it seemed Firefox was having trouble with both the break-inside and flex CSS on the same div. I separated them, and my masonry started to work. Thanks.
