Current behavior:
In my app, I have a list with virtual scroll. When the user taps on an item, a sub-page is shown. When the user taps the back-button, the list is show again. So far so good.

But when the user changes the device's orientation (e.g. from portrait to landscape) on the sub-page and taps back afterwards, the list is shown with only one item.

Expected behavior:
After going back, again the whole list should be shown. Maybe repositioned to the beginning (like the behaviour, when I rotate the device showing the list).

Steps to reproduce:

Hello,

I have the same problem.

As complementary information, the items on the list stack up, which is why we only see one element
