"description":"In Safari, the height of (non flex) children are not recognized in percentages. However other browsers recognize and scale the children based on percentage heights. ([See bug](https://bugs.webkit.org/show_bug.cgi?id=137730)) The bug also appeared in Chrome but was fixed in [Chrome 51](http://crbug.com/341310)"

},
{
"description":"Safari 10 and below uses min/max width/height declarations for actually rendering the size of flex items, but it ignores those values when calculating how many items should be on a single line of a multi-line flex container. Instead, it simply uses the item's flex-basis value, or its width if the flex basis is set to auto. [see bug](https://bugs.webkit.org/show_bug.cgi?id=136041). Fixed in all versions > 10."
