Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/43599
iOS E2E tests non-deterministic rendering happens around examples with a border set to `StyleSheet.hairlineWidth`. That value has special subpixel math, that doesn't seem to render consistently on iOS (this is its own bug).
To unblock adding some new E2E iOS TextInput tests, this removes usage of `hairlineWidth` in styles, and more generally, tries to unify TextInput styles in the examples.
This will break a whole bunch of RNTester Jest E2E baselines on different apps, which I will update from land-time runs or after continuous builds are available for different endpoints.
