Hi all! I've created a CodePen that shows off a panel animation I'm working on for the backend of my app (obviously simplified for demonstration). If you click through with the buttons on the top (have a large screen so you can see the convo view slide over with the inbox view still there) you'll notice I'm animating the panel widths with flexBasis. On resize EVERYTHING is jumping around when Chrome hits half-pixels (look at the sample convo and button, as well as the pseudo selector text).
