Jakub Piasecki	d4b36b0300	Fix `display: contents` nodes not being cloned with the wrong owner (#52530 ) Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/52530 This PR fixes two issues with `display: contents` implementation: 1. When a node with `display: contents` set is a leaf, it won't be cloned after the initial tree is built. The added test case covers this scenario. 2. It was possible for the subtree of `display: contents` nodes not to be cloned during layout. I don't have a minimal reproduction for this one, unfortunately. It was discovered in the Expensify app: https://github.com/Expensify/App/issues/65268, along with a consistent reproduction. In that specific case, it seems to be heavily tied to `react-native-onyx`, which is a state management library.
