[Bug]: Latest turn cannot be selected with the mouse on Arch Linux / Hyprland

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/desktop

Steps to reproduce

Observed in an existing thread on Arch Linux with Hyprland:

1. Open the T3 Code desktop app, version 0.0.42.
2. Open a thread whose latest turn is 39.
3. Open the turn navigation list.
4. Move the mouse over turn 38, then over turn 39, and try clicking turn 39.

This is the observed case; it is not yet known whether the problem depends on the number of turns or reproduces in a fresh thread.

Expected behavior

The latest turn should highlight under the mouse and be selectable by clicking, just like the preceding turn.

Actual behavior

Turn 38 is the last item that can be highlighted and selected with the mouse. The pointer itself moves normally over turn 39, but that list item does not highlight/select, and clicking it has no effect. As a result, the latest turn cannot be selected through the list with the mouse.

Impact

Mouse navigation to the latest turn is blocked in the affected thread. Earlier turn selection still works.

Version or commit

0.0.42

Environment

T3 Code desktop app on Arch Linux with Hyprland.

Workaround

No workaround confirmed. Keyboard navigation has not been verified.

Start in apps/desktop by reproducing the issue in the 0.0.42 turn navigation list, comparing hover and click behavior for turns 38 and 39. Trace the turn-list entry point and verify that the latest turn highlights and can be selected with the mouse without breaking earlier turns.
