Jetpack Compose version: BOM 2024.09.00

Jetpack Compose component(s) used: LazyColumn and a focusable item like Button

Android Studio Build: Android Studio Koala | 2024.1.1 Patch 1

Kotlin version: 2.0.20

This is a duplicate of https://issuetracker.google.com/issues/365706545. It's not receiving any attention in the foundation component so I'm trying in the TV component instead. This is a blocker for us for bumping to Compose 1.7 so we would really like to see this fixed. Please close one of the issues depending on where it belongs best.

Please see this sample repo: https://github.com/hakonschia/compose-1.7-focus/blob/main/app/src/main/java/com/example/scrolling/MainActivity.kt

This is for TV apps where you navigate focusable items with a DPAD

When you click on an item in a LazyColumn so that you navigate to a different framgent then focus automatically transfers to a different item (I believe it sets it to the first visible item the LazyColumn has). This does not happen on BOM 2024.08.00 (1.6.8) and is new in 2024.09.00 (1.7.0)

On 2024.09.00 this is logged. When moving to fragment B then "Button 7" recieves focus, which is not from a user interaction

12:48:56.368 Scroll...xample  D  Button 7 has focus
12:48:56.376 Scroll...xample  D  Button 7 has focus

On 2024.08.00 this is logged, as expected focus does not move away from "Button 10":

12:53:22.687 Scroll...xample  D  Button 0 has focus
12:53:23.378 Scroll...xample  D  Button 1 has focus
12:53:23.676 Scroll...xample  D  Button 2 has focus
12:53:23.915 Scroll...xample  D  Button 3 has focus
12:53:24.075 Scroll...xample  D  Button 4 has focus
12:53:24.249 Scroll...xample  D  Button 5 has focus
12:53:24.424 Scroll...xample  D  Button 6 has focus
12:53:24.898 Scroll...xample  D  Button 7 has focus
12:53:29.723 Scroll...xample  D  Button 8 has focus
12:53:30.022 Scroll...xample  D  Button 9 has focus
12:53:30.497 Scroll...xample  D  Button 10 has focus
12:53:33.823 Scroll...xample  D  Moving to B

In our app this is pretty noticeable as the list clearly scrolls and we lose the focus position, so when we return to the fragment the scroll position isn't on the item the user clicked
