Vertical scroll bar in timeline tree view don't scroll to the bottom of the users list

Hi team,
I set a tree timeline view with a DB call to show a list of users.
The vertical scroll bar don’t scroll to the bottom of the list.
Is there a way scroll to the bottom of the list ?

Hi,

Scroll should work correctly by default. Please reproduce the issue using the snippet system and share with me the updated link. It will help me to understand what goes wrong

Hi Polina,
Many thanks for your support.
I fix my issue during this week-end.
The problem was because I create a timeline with an header.
I change the original style height from 100% to 92% and all run correctly.
Thanks.
