* Expose LegacyHidden type I will use this internally at Facebook to migrate away from <div hidden />. The end goal is to migrate to the Offscreen type, but that has different semantics. This is an incremental step. * Disable <div hidden /> API in new fork Migrates to the unstable_LegacyHidden type instead. The old fork does not support the new component type, so I updated the tests to use an indirection that picks the correct API. I will remove this once the LegacyHidden (and/or Offscreen) type has landed in both implementations. * Add gated warning for `<div hidden />` API Only exists so we can detect callers in www and migrate them to the new API. Should not visible to anyone outside React Core team.
