In which task and step of the codelab can this issue be found? After implementing Step 6 and later, also in the main branch

Describe the problem When a DogItem is scrolled off-screen, it's expanded state is not retained. This is probably caused by LazyColumn destroying the DogItem and its contained state when it goes off-screen and re-creating it when it comes back into view.

Steps to reproduce?

  1. Check out the main branch
  2. Build and launch app
  3. Click on first DogItem to expand it
  4. Scroll to bottom of the list
  5. Scroll back up again, see that the item is now collapsed
