[Bug]: Empty tab bar area cannot drag the window on macOS

[Autumn0716]

Preflight

• I searched existing issues and did not find a duplicate.
• I am on OpenKnowledge 0.49.2.

What happened?

In the macOS desktop app, dragging the unused area of the top tab bar/title bar does not move the application window.

The affected area is the blank space between the + button and the controls on the right (such as Share and Settings). It is visually unused, but pressing and dragging there has no effect.

Expected: unused space in the top bar should act as a native window drag region. Interactive controls such as +, Share, and Settings should remain clickable and excluded from the drag region.

Actual: dragging the blank area does not initiate a window move.

Steps to reproduce

1. Open the OpenKnowledge desktop app on macOS.
2. Find an unused area of the top tab bar between the + button and the controls on the right.
3. Press and hold in that blank area, then move the pointer.
4. Observe that the application window does not move.

Thanks for the report. This is a regression we accidentally introduced recently. We are working on a fix and will have one soon.
