Buttons aligns right in Firefox but not in Chrome

Question

I'm trying to have my buttons vertically centered but horizontally aligned to the right. It is important that it is responsive! It works in Firefox but not in Chrome. Here's my JSFiddle: https://jsfiddle.net/enLcogy2/4/

I had a similar problem once, but this time position doesn't seem to help. Any ideas?

Apparently right and left for justify-content works currently only in firefox so it is better to use flex-end
