TUI search: description panel resets scroll to top after scrolling

[SorraTheOrc]

Summary: When viewing search results in the TUI, the description panel does not retain the user's scroll position. After scrolling down and stopping, the panel snaps back to the top, preventing reading long descriptions.

Steps to reproduce:

1. Open the TUI application and perform a search that returns results with long descriptions (so the description panel is scrollable).

2. Select a search result so the description is visible.

3. Scroll down inside the description panel and then stop scrolling.

4. Observe that the description unexpectedly jumps back to the top.

Observed behavior: Description panel resets to top after scrolling stops.

Expected behavior: Description panel should keep the scroll position until the user scrolls or another explicit navigation occurs.

Impact: Blocks reading long descriptions in the TUI search results; poor UX. Reproducible and disrupts core flows.

Acceptance criteria: - Scrolling the description panel no longer snaps back to the top once user stops scrolling. - Manual QA steps to reproduce no longer show the issue.
