Can't keep a screen mounted

Current Behavior

From the docs:

navigation.navigate({ name: SCREEN, key: SCREEN_KEY_A });
navigation.navigate({ name: SCREEN, key: SCREEN_KEY_B });
navigation.navigate({ name: SCREEN, key: SCREEN_KEY_C });
navigation.navigate({ name: SCREEN, key: SCREEN_KEY_D });

then

navigation.navigate({ key: SCREEN_KEY_A }); // will go to screen A FROM screen D

It will unmount B, C and D. (btw I think this should be highlighted more in the docs)
What if I want to keep let's say D mounted? And when I navigate to D again, I want to reuse the same instance.

My use case is a webview that I want to keep mounted in the background.
I found an old question in stackoverflow, never answered https://stackoverflow.com/questions/41818857/keep-react-native-webview-mounted

Expected Behavior

• I want to have the option to keep a screen mounted and reuse the same instance when I navigate back to it.

Issue の navigation.navigate の例から始め、記載されている WebView のユースケースについて、リンク先の Stack Overflow の質問を確認してください。画面のマウントと再利用がどこでドキュメント化または設定されているかを特定し、そのうえで、想定されるオプションとマウントされた画面への影響が明確になるように動作またはドキュメントを更新してください。
