bug with @react-navigation/bottom-tabs - initial jumping and flickering

Description

When I'm using @react-navigation/bottom-tabs with the native stack navigator, the header jumps on android and sometimes flickers on iOS on tab change (on the first render only). But it doesn't happen if I use the JS stack navigator.

I wrapped NavigationContainer with SafeAreaProvider like this:

<SafeAreaProvider initialMetrics={initialWindowMetrics}>
      <NavigationContainer>
        <RootStack />
      </NavigationContainer>
</SafeAreaProvider>

I also patched react-navigation bottoms tabs with this PR applied by @WoLewicki
react-navigation/react-navigation#9772

If I remove initialWindowMetrics jump on Android is gone, but on iOS, the header is still flickering.

it maybe related to this issue

Steps To Reproduce

1. Open app.
2. Click on Tab2.
3. See the position of the header.

Expected behavior

the header should not jump on android and flicker on iOS(on initial render).

Actual behavior

Start with the linked reproduction repository and run the flow using @react-navigation/bottom-tabs with the native stack, comparing initialWindowMetrics behavior in SafeAreaProvider against the JS stack. Reproduce the first tab change on Android and iOS, then verify that the header no longer jumps or flickers on the initial render.
