Generalization of `isInAParentText` context Summary: Currently `isInAParentText` context works as imaginary `isInAAncestorText` context (not like a real `isInAParentText`). Let's imagine we have hierarchy like: `View -> Text -> Text* -> View* -> Text* -> Text* -> View` With current implementation all nodes marked with asterisk have `isInAParentText` context, which is incorrect (because some of them actually in View context). With the new implemetations it will work like this: `View -> Text -> Text -> View* -> Text -> Text* -> View*` So, only nodes which have <Text> (or <TextInput>) as a parent will have `isInAParentText` context. This change allows to select proper `Text` vs. `VirtualText` component in cases where <Text> and <View> components can interleave each other.
