That appears to do the trick, thanks! Can I expect automagic flex vendor prefixes to show up eventually?

I'm using GSAP to tween a few objects from { flex: 0 } to { flex: whatever }. I'm well aware that flex is still in flux, but hey ... I live dangerously. This works flawlessly on modern desktop browsers, but fails on mobile safari. It looks like mobile safari (latest version) still requires the -webkit- prefix. From what I understand, the GSAP CSS plugin should handle vendor prefixes, but it looks like it's skipping over this one. Is there a way I can specify the prefix in the meantime? Edit: Added pen, click "Grow/Shrink" to make the magic happen.
