Strange behavior of SfListView when filtering
Hi. I'm having a strange issue with SfListView. I'm not able to say exactly when it started to appear. It was working fine and we only noticed the problem recently. SfListView is inside a grid with a search bar at the top. It's filtered when user type in search bar. Everything works correctly, except in a given situation. When we type, suddenly, there's a huge blank space before the first item (the items seams to be moved to bottom). If we continue filtering, it refreshes and first item get its position correctly.
Here are some screenshots. Everything is fine when typing "swis" in the search bar. When I type "swiss", the problem occurs, although the number of found items doesn't change. If I continue and type "swiss d", it reverts to a correct position when filtering the last found item.
The problem does not depend on the number of items displayed. It can occur with one or more items. But only if items are not filling the height available. I've tried to disable sticky group header, tried to remove group header, tried to change item template, etc. Nothing seems to fix the problem. Based on these screenshots, are you able to point me to the right direction to fix this?
