fix: buggy behaviour of search bar / large title on Fabric with native stack v7

[kkafar]

Motivation

UIKit requires ScrollView to be at index 0 in given view's subview array to enable it's interaction with navigation bar. On Fabric DebugContainer view got flattened, however it was not removed from hierarchy -- instead the view was attached as first child of the RNSScreenView disabling system interaction between navigation bar and a scroll view.

See

• fix(iOS): buggy search bar / large title behaviour on Fabric software-mansion/react-native-screens#1825

for broader context and explanation.
