TabDisposable with nested/parent navigation loses Screen state

[creativedrewy]

When navigating from inside a TabNavigator after locating a parent/outer Navigator, the Tabs will always be disposed by TabDisposable, resulting in the screen state being lost for the tabs. This issue occurs even if the outer/parent Navigator has disposeNestedNavigators = false set.

You can utilize the attached patch file to see the bug in action:
