Summary: Sometimes, when we implement some custom RN view, we have to proxy all accessible atributes directly to some subview which actually has accesible content. So, in other words, this allows bypass some axillary views in terms of accessibility. Concreate example which this approach supposed to fix: https://github.com/facebook/react-native/pull/14200/files#diff-e5f6b1386b7ba07fd887bca11ec828a4R208 Reviewed By: mmmulani Differential Revision: D5143860 fbshipit-source-id: 6d7ce747f28e5a31d32c925b8ad8fd4b98ce1de1
