Supporting calc() in flexbox is now on the Microsoft Edge backlog.Greg Whitworth [MSFT] commented
Can you please provide me a repro of what this is referring to. I don't think there is a gap in this space any longer, especially since this is pre Edge, I think this has been fixed - but before closing it I want to reach out and ensure you weren't referring to something that we hadn't covered. Thanks!
