Summary: X-link: https://github.com/facebook/react-native/pull/44010 Pull Request resolved: https://github.com/facebook/yoga/pull/1641 Yoga has quirk where newly constructed nodes are clean, which isn't really correct. Normally never shows in in real code because setting a style or children will dirty. Fabric doesn't use the public APIs that do this dirtying, so it ends up getting creative instead. We should fix so that newly constructed nodes are dirty. Copy-constructed Nodes (also only a Fabric thing, will retain original dirty flag.
