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.

Start with the navigation.navigate example in the issue and review the linked Stack Overflow question for the stated WebView use case. Determine where screen mounting and reuse are documented or configured, then update the behavior or documentation so the expected option and its effect on mounted screens are clear.
