3 years ago Hi @jpnurmi, Thanks for filing the issue. I can reproduce the issue on stable 2.5.2 and the master 2.6.0-12.0.pre.299 channel. After page up/ down the focus doesn't work with arrow keys until the currently focused item is brought into view by either scrolling via mouse / page (up/down)
Note: The moment in the video when the scroll is stopped is when I am pressing the arrow keys at 09:00 , 19:00 which doesn't work unless scrolled to focused item
Directional focus traversal no longer works. Nothing happens.
Can you please point the version where it worked in the past it might help to track down the change that affected it.

Directional focus traversal stops working when a focused item is scrolled outside the list view's cache extent.
Steps to Reproduce
Expected results:
The list view is scrolled back to the focused item and focus traversal continues from where it was.
Actual results:
Directional focus traversal no longer works. Nothing happens.
