Summary: Pull Request resolved: https://github.com/facebook/yoga/pull/1317 X-link: https://github.com/facebook/react-native/pull/37374 This is edge-casey enough, and I actually broke this in D42282358 without us noticing (I changed height to width of the bottom usage, instead, copy/pasting the value of the top one).
