Summary: We previously fixed Differentiator generating an incorrect parentTag (react#48055), but this can lead to crashes in Android UI due to reordering that happens in the Android mounting layer. While we have an experiment to disable this reordering (react#46702) this currently has a negative performance impact which needs to be addressed. As a mitigation, we can make the lookup of parentTag's ViewManager state nullable. We only require this to support `needsCustomLayoutForChildren`, which is not commonly used, and seems acceptable to drop in this scenario.
