Hey, thanks for the report. This is a known bug from the scroll-reset cluster. When you toggle or hide or show the agents panel, the chat remounts and scrolls to the top instead of keeping the position at the bottom. The Ctrl+Alt+J option moves more than a regular tab switch because it does a full remount of the panel.
The issue is reported and tracked, but I can’t share a timeline for the fix yet.
As a temporary workaround, if you don’t collapse the agents panel using the shortcut and keep it open, the remount won’t trigger and the position won’t reset.
Updating to the current version won’t fix this specific case, but it’s still worth installing for other fixes. If there’s progress on this problem, I’ll reply here.
