Retain scroll position when returning to 'Set up a new integration' list

[coolssor]

Currently when returning to the 'Set up a new integration' list after clicking the back button during the setup of an integration, it returns you to the top of the list.

To return to the original position it often requires further scrolling due to the large amount of integrations available.

Clicking the back button should return you to the previous position you were in the list.

To reproduce the issue

1. Navigate to Settings > Devices & services > Integrations
2. Click Add Integration
3. Select an entry that has a back button (for example Google)
4. Click the back button
   • You should see that it returns you back to the top of the list instead of the previous scroll position
